In Canada, 72% of the voters are not in favour of the reinstatement of the deathpenalty. a) If three voters were selected at random what is the probability that  exactly 2 were not in favour of the death penalty, at most 2 were not in favour of the death penalty and at least 2 were not in favour of the death penalty. b) Suppose that a sample of n = 500 cases are observed. Let pˆ denote the proportion ofvoters in this sample not in favour of the reinstatement of the death penalty.
