4. A branch of a certain bank in Davao 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: x<0 .06 0sx< 1 .19 1sx< 2 .39 2sx<3 F(x) = .67 3 sx< 4 .92 4 sx<5 .97 5sx<6 1 6 5x 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)
