An office has four copying machines, and the random variable X measures how many of them are in use at a particular moment in time. Suppose that P(X= 0) = 0.08, P(X= 1) = 0.11, P(X=2) = 0.27, and P(X= 3) = 0.33 (a) What is P(X= 4)? (b) Draw a line graph of the probability mass function. (c) Construct and plot the cumulative distribution function.
