Abranch of a certain bank 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: f(x) = 0 x < 0 0.05 0 ≤ x < 1 0.22 1 ≤ x < 2 0.38 2 ≤ x < 3 0.53 3 ≤ x < 4 0.83 4 ≤ x < 5 0.99 5 ≤ x < 6 1 6 ≤ x calculate the following probabilities directly from the cdf: (a) p(2), that is, p(x = 2) (b) p(x > 3) (c) p(2 ≤ x ≤ 5) (d) p(2 < x < 5)
