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.

Discrete probability distributions Discrete uniform distribution Binomial distribution

Understand and use the Normal distribution as a model; find probabilities using the Normal distribution.

Link to histograms, mean, standard deviation, points of inflection and the binomial distribution.

Normal distribution Approximating the binomial distribution

Select an appropriate probability distribution for a context, with appropriate reasoning, including recognising when the binomial or Normal model may not be appropriate.

Use probability distributions in context
