Now we will calculate binomial probabilities using RStudio. Recall that if X~ B(n, p) then the formula to calculate P(X = k) is: P(X= k) = (2) pk (1 − p)n-k We have used this formula a number of times in lectures and tutorials. This is also quite easy to compute in Rstudio. Learn how to compute binomial probabilities by working through: • Section R5.5 - Evaluating a binomial probability. In the following questions, we assume that 66 % of males use auction sites. a) What is the probability that exactly 5 of the 9 males (in the random sample) use internet auction sites, correct to at least three decimal places? 0.211 b) What is the probability that at most 5 of the 9 males (in the random sample) use internet auction sites, correct to at least three decimal places? 0.366 c) What is the probability that more than 5 of the 9 males (in the random sample) use internet auction sites, correct to at least three decimal places?
