This is part of the HSC Mathematics Extension 1 course under the topic: The Binomial Distribution.

##### Some definitions:
• Sample proportion: the number of favourable outcomes/successes
• Sampling distribution: probability distribution made from a larger number of samples.
• Binomial random variable: number of successes in n repeated trials of a binomial experiment.

A binomial distribution has 3 main characteristics

• n the number of trials
• p the probability of success
• 1-p the probability of failure.
