understand the concepts of Bernoulli trials and the concept of a binomial random variable as the number of βsuccessesβ in π independent Bernoulli trials, with the same probability of success π in each trial
4.3.2.2
identify contexts suitable for modelling by binomial random variables
4.3.2.3
determine and use the probabilities π(π=π) = {nr} π^π(1 β π)^(n-r) associated with the binomial distribution with parameters π and p
4.3.2.4
calculate the mean πp and variance πp(1βπ) of a binomial distribution using technology and algebraic methods
