These are the Transum resources related to the statement: "Understand and use simple, discrete probability distributions (calculation of mean and variance of discrete random variables is excluded), including the binomial distribution, as a model; calculate probabilities using the binomial distribution".

Here are some specific activities, investigations or visual aids we have picked out. Click anywhere in the grey area to access the resource.

- Pascal's Triangle Get to know this famous number pattern with some revealing learning activities
- Plinko Probability A simulation of a Quincunx (Galton Board) which can be used to create the bell shaped curve of the normal distribution.

Here are some exam-style questions on this statement:

- "
*Mr Willis goes to school (he's a Maths teacher) five times each week during term time. On any given day, the probability that he goes on an orange bus is \( \frac13 \).*" ... more - "
*A small digital storage manufacturer makes novelty USB drives which are given away at conferences. The probability that a drive is defective is 0.03. The factory tests a random sample of 200 drives.*" ... more - "

If you use the TI-Nspire calculator you can find instructions for performing binomial distribution calculations on the GDC Essentials page.

Additional note: The so-called "Pascalâ€™s triangle" was known to the Chinese mathematician Yang Hui much earlier than Pascal.
