the general case, useful questions like these, we need to build a new function called the Cumulative Distribution Function (CDF). The CDF of W will return the probability that the value of W is at most k for k=0,1,2,3, or 4. There is an easy way to build the CDF if you know the PMF: The CDF for W=k
