1-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.Define the cumulative distribution function of a random variable X.
c.Calculate the cumulative distribution function F(0),...... and F(4).
