Popular with Sunnybank families ## Primary, secondary and senior maths The three courses Sunnybank families ask about most; the full list is lower down.

When you pick two different people, the second pick comes from a slightly smaller group. Whether that matters depends on how big the group is. The 2021 Census counted **1,119** Sunnybank residents in tertiary education, of whom **682** were at university and 432 in vocational education. Without replacement, the chance that two different tertiary students chosen at random are both at university is (682 × 681) / (1,119 × 1,118). With replacement, which treats the two picks as independent, it is (682 / 1,119) squared. | Method | Calculation | Probability | About 1 in | | --- | --- | --- | --- | | Both at university, without replacement (exact) | (682 x 681) / (1,119 x 1,118) | 0.37124 | about 0.37 | | Both at university, with replacement (shortcut) | (682 / 1,119) squared | 0.37146 | about 0.37 | | Both in vocational education, exact | (432 x 431) / (1,119 x 1,118) | 0.14883 | about 0.15 | | Both in vocational education, shortcut | (432 / 1,119) squared | 0.14904 | about 0.15 | ### Here the shortcut wins In a group of over a thousand, removing one person barely changes the odds. The with-replacement shortcut is quicker and only 0.06% off for the university pair, which is plenty accurate. ### In a small group it fails Take a class of 10 with 3 students in Year 12. Without replacement the chance both picks are Year 12 is 6/90, about 0.067; the shortcut gives 0.09. That is 35% too high. ### The rule of thumb When the sample is a tiny fraction of the group, the shortcut is safe. When it is a noticeable fraction, use the exact method. ### What students practise Tree diagrams, multiplying along branches, the difference between independent and dependent events, and comparing an exact answer with an approximation. Senior students meet the same ideas in the binomial and related distributions. ### Why use real counts Made-up numbers hide the question that matters: is the group big enough for the shortcut? Real Census counts make students decide. The counts are as the ABS published them; the probabilities are our own calculation. Data: ABS, [2021 Census QuickStats, Sunnybank](https://abs.gov.au/census/find-census-data/quickstats/2021/SAL32694), read 14 October 2026. Checking by experiment ## Simulating the draw in Python A formula gives the probability; a simulation shows what happens in practice. Older students do both and compare. | Number of repeats | Times both were at university | Observed proportion | Exact probability | | --- | --- | --- | --- | | 1,000 | 371 | 0.371 | 0.37124 | | 100,000 | 37,294 | 0.37294 | 0.37124 | ### What the simulation shows With 1,000 repeats the observed proportion, 0.371, happens to land very close to the exact value. With 100,000 repeats it is 0.37294, which is still within the normal wobble of a random experiment. Students learn that simulations get closer to the truth on average as repeats grow, but never land on it exactly. ### Why it is worth doing Writing ten lines of Python to draw two names from a list makes "without replacement" concrete: the code literally removes the first name before drawing the second. Students taking [maths through coding](/courses/maths-through-coding) build this as one of their first probability projects. Years 11 and 12 in Queensland ## Senior maths for Sunnybank students Queensland students study senior subjects across Units 1 to 4. University entry requirements show which maths subject many courses expect. ### Mathematical Methods and university entry The University of Queensland lists, for its Bachelor of Science, the prerequisites "Queensland Year 12 (or equivalent): General English subject (Units 3 & 4, C) Mathematical Methods (Units 3 & 4, C)" together with a science subject. So Mathematical Methods matters for many science, engineering and economics pathways, and it is the senior subject we are asked about most. ### What we teach, and what we do not promise We teach senior maths content, exam technique and checking habits, for Mathematical Methods and the other senior maths subjects. We never promise a result or an ATAR. Internal assessments remain the student's own work. The Queensland Curriculum and Assessment Authority publishes the full list of senior subjects; its pages did not load for us when we checked, so we do not list the other maths subjects here from memory.

Prep to Year 10 ## What Sunnybank learners build before senior school Probability starts long before Year 11, with words like likely and unlikely, and grows into fractions, tree diagrams and data. | Years | Chance and data focus | A typical task | | --- | --- | --- | | Prep to 2 | Likely, unlikely, certain, impossible | Sorting everyday events by how likely they are | | 3 to 6 | Fractions as chances, simple experiments | Rolling a dice 60 times and comparing with 1/6 | | 7 and 8 | Sample spaces and relative frequency | Listing outcomes for two coins | | 9 and 10 | Two-step events, with and without replacement | The Sunnybank question above | ### Sunnybank learners in 2021 The Census counted 611 Sunnybank residents at primary school and 518 at secondary school, and 477 residents aged 15 to 19, the years when senior maths choices are made. Online lessons mean every one of them could join from home. ### Academies and tests Year 9 families interested in the Queensland Academies can read our [Queensland Academies entry maths](/queensland-academies-entry-maths-practice) page. NAPLAN numeracy has [its own page](/naplan-numeracy-practice-online). This page stays with everyday maths. Calendar and clock ## The 2027 Queensland school year, on Brisbane time Queensland keeps the same clock all year, which makes lesson times simple. | Term | Dates | Length | | --- | --- | --- | | Term 1 | Wednesday 27 January to Thursday 25 March | 9 weeks | | Term 2 | Monday 12 April to Friday 25 June | 11 weeks | | Term 3 | Monday 12 July to Friday 17 September | 10 weeks | | Term 4 | Tuesday 5 October to Friday 10 December | 10 weeks | ### No daylight saving Brisbane does not change its clocks, and neither does India, where our teachers work. So the gap is the same all year: Brisbane is 4 hours 30 minutes ahead. A 5pm Sunnybank lesson is always 12:30pm for the teacher. Families in New South Wales see the gap move twice a year; Sunnybank families do not. ### One to one or in a group Private lessons suit a specific gap or an exam. Groups of fifteen to twenty at one level suit steady progress, and the shared board shows the teacher every step. Holiday revision is available on request.

Adults in Sunnybank ## Probability and statistics for grown-ups Many adults who join us want to read numbers with confidence: risks, averages and percentages in the news and at work. ### Reading risk Understanding what a one in a thousand chance means, and why two small risks are not simply added together. ### Workplace data Averages, spread and simple charts for reports, with the habit of asking how a number was produced. ### Supporting a student Following tree diagrams and probability tables well enough to help a teenager with homework. Adult learners have their own classes, separate from school students, or private lessons at a time that suits shift work. The with-and-without replacement question above is a favourite first lesson for adults too, because it shows that a sensible shortcut has limits. Progress ## From likely and unlikely to Mathematical Methods Learners step up once a skill works on a problem they have not met before. | Usually | Step | Shown when the learner can | | --- | --- | --- | | Prep to Year 2 | 1. Language of chance | Place events on a likely-to-unlikely line and explain why | | Years 3 to 6 | 2. Chance as a fraction | Write the chance of rolling a 5 and test it | | Years 7 to 10 | 3. Two-step events | Decide whether replacement matters and calculate both ways | | Years 11 and 12 | 4. Distributions | Use a probability model and judge whether it fits | ### Coming in at Year 11 Students who join late often need algebra and fractions shored up first; we say how long that should take. It is the quickest path to coping with senior work. ### Adults Adults often come for statistics at work or to help with homework. They learn in adult groups or one to one.

Ritu Kedia Parent Sunnybank maths questions ## Questions about a maths tutor in Sunnybank ### Do you tutor maths for Sunnybank students? Yes, live online in Brisbane time, from Prep to Year 12 and for adults, one to one or in level-matched groups. ### Do you teach Mathematical Methods? Yes, along with the other senior maths subjects and Years 7 to 10 maths. ### Why do universities mention Mathematical Methods? Many list it as a prerequisite. The University of Queensland, for example, lists Mathematical Methods (Units 3 and 4, C) among the prerequisites for its Bachelor of Science. ### What is the difference between with and without replacement? Without replacement, the second pick comes from a group one smaller. For two Sunnybank tertiary students both at university, the answers are 0.37124 exact and 0.37146 with the shortcut. ### When is the with-replacement shortcut safe? When you choose only a tiny fraction of the group. In a class of 10 the shortcut can be a third out; for over a thousand Sunnybank tertiary students it is about 0.06% out. ### Can tutoring guarantee a result or ATAR? No. We teach carefully and report honestly, but no tutor can promise a result or an ATAR. ### Do lesson times change during the year? No. Brisbane has no daylight saving, so lessons stay at the same time all year. ### Can adults learn too? Yes, in adult groups or one to one. ### Can a simulation replace the formula? No, but it is a good check. In our 100,000-repeat simulation the proportion of university pairs was 0.37294, close to the exact 0.37124. ### What is a tree diagram used for? It lays out each stage of a chance experiment as branches, so probabilities can be multiplied along a path and added across paths. It makes with and without replacement easy to compare. ### How much are lessons? The first lesson is free. Monthly fees for groups and private lessons are in the fees panel on this page.
