Requirements
  • For students wanting to cover the unit 1/2 content of this course, there are no course requirements, although a basic understanding of probability would be useful.
  • For students wanting to cover the unit 3/4 content of this course, they need to have a sound understanding of the unit 1/2 content of probability (with an exception for ‘permutations’ as it is not part of the unit 3/4 course).
  • Moreover, unit 3/4 students need to be able to sketch the graphs of basic functions (including hybrid functions), and evaluate definite integrals. This is necessary for the lectures under the topic ‘continuous random variables’.
  • A graphics calculator is generally required for the unit 3/4 content.
Description

After going through this course, you will be able to understand how probability works at an Australian VCE Maths Methods Units 1-4 level, and apply such knowledge on exam questions. Each lecture includes many clearly annotated diagrams to make mathematical concepts easier to understand, and will be followed by a quiz to test your understanding.

The lectures are designed to cater for both unit 1/2 students and unit 3/4 students, with the unit 1/2 and unit 3/4 content indicated at the beginning of each ‘section’ of this course. Unit 1/2 students only need to watch the unit 1/2 content of each lecture, although you may go on to watch the unit 3/4 content if you want to get a head start. Unit 3/4 students may find the unit 1/2 content a good revision for them.

You are encouraged to go through the lectures in order since the content from the earlier lectures is often required in the later lectures.

Who is the target audience?
  • This course mainly caters for students doing the Australian VCE subject, Mathematical Methods unit 1/2 and 3/4.
  • However, students from other countries or Australian states at a level equivalent to year 11 and 12 in Australia may also find this course useful.
  • This course will clearly outline the content from unit 1/2 and unit 3/4, although sometimes there is a slight overlap between the two. For unit 1/2 students, you can also watch the unit 3/4 content to get a head start for the future; while for unit 3/4 students, you can also watch the unit 1/2 content if you need some revision on the previously learnt material.

Unit 1/2 Probability
7 Lectures 01:26:51

This lecture introduces the basics of probability that you would have covered in year 10. You will learn how to write down a sample space, distinguish between mutually exclusive events and independent events, and draw tree diagrams. 

If you don’t have a very strong foundation on probability, this lecture will act as a good revision for you. However, unit 3/4 students are also highly encouraged to watch the example involving tree diagrams (from 10:34 minutes onwards) as it acts as a good exam question.

Probability basics (including tree diagrams)
6 questions

This lecture introduces the addition law of probability, and teaches you how to draw Karnaugh maps. It also covers how Pr(A∩B) = 0 for mutually exclusive events, and how Pr(A∩B) = Pr(A) × Pr(B) for independent events.

This lecture introduces the concept of conditional probability, and teaches you how to apply the concept on theory-based (formula-based) questions and worded problems.

Conditional probability
3 questions

This lecture introduces the addition and multiplication principles to calculate the number of ways a task can be performed (e.g. creating a three-digit number from the digits 1, 2, 3, 4, 5 and 6), which can be subsequently used to calculate probabilities. Moreover, factorials are introduced at the end of this lecture, which is necessary for the next two lectures.

This lecture teaches you how to count using permutations (nPr), which enables you to calculate the number of ways ‘r’ objects can be selected from ‘n’ objects where order is important. Moreover, it will include calculation of probabilities involving permutations.

This lecture teaches you how to count using combinations (nCr), which enables you to calculate the number of ways ‘r’ objects can be selected from ‘n’ objects where order is NOT important. Part one of this lecture will introduce the basics of combinations, and teach you how to calculate combinations (e.g. 10C4).

Maths Tutor

I am a 1st year medical student in the University of Melbourne (as of 2017), and I have completed three years of Bachelor of Biomedicine. I have had three years of experience providing one-on-one maths tutoring at an Australian year 11-12 level, for the subjects of Maths Methods and Specialist Maths. When tutoring, I like to explain the steps that lead to the final answer in a clear and logical manner, and I try to make my lessons as engaging as possible. I have used the same style of tutoring my students Maths Methods in these videos, so I hope you find them highly useful!
