A branch of a certain bank in New York City has six ATMs. Let X represent the number of machines in use at a particular time of day. The cdf of X is as follows. Calculate the following probabilities directly form the cdf: (i) p(2), that is, P(X = 2); (ii) P(X > 3); (iii) P (2 ≤ X ≤ 5); (iv) P(2 < X < 5). 0 x < 0 0.06 0 ≤ x < 1 0.19 1 ≤ x < 2 F(x) = { 0.39 2 ≤ x < 3 0.67 3 ≤ x < 4 0.92 4 ≤ x < 5 0.97 5 ≤ x < 6 1 6 ≤ x
