I need some help with this question. The d.) section  for the question

A branch of a certain bank has six ATMS. Let X represent the number of machines use at a particular time of day. The cdf of X is as follows: X < 0 0 < x < 1 1 < x < 2 2 < x < 3 3 < x < 4 4 < x < 5 5 < x < 6 6 < x 0.07 0.21 0.42 F(x) = 0.69 0.82 0.96 1 Calculate the following probabilities directly from the cdf: (a) p(2), that is, P(X = 2) 0.21 (b) P(X > 3) 0.31 (c) P(2 < X < 5) 0.75 (d) P(2 < X < 5)
