Tyrone is the manager of an independent gym that operates a membership scheme and runs a small number of weekly group exercise classes for members. Using class attendance data, Tyrone constructs a discrete probability distribution for the random variable X, the number of classes attended in a particular week per member. x 0 1 2 3 4 p(x) 0.1 0.2 0.35 0.25 0.1 (a) Confirm that this is a valid p.m.f. by showing how p(r) satisfies all the requirements for a valid p.m.f. (b) Write down a table containing values of F(r), the cumulative distribution function (c.d.f.) of X, for x = 0, 1,2,3,4 (c) Using the c.d.f. find the probability that a gym member attends at least 2 classes per week
