The probability of a person contracting the flu on exposure is 0.4. Let a success be a person contracting the flu. Consider the binomial distribution for a group of 5 people that has been exposed.
(a) Find the probability mass function.
(b) Compute p(x) for x = 0, 1, 2, 3, 4, 5.
(c) Find the mean and the standard deviation.
(d) Find the mode.
(e) Find the median.
