Let the random variable X = number of phone calls you will get in the next 24 hours. Suppose the possible values for X are 0, 1, 2, or 3, and their probabilities are .1, .1, .3, and .5, respectively. For instance, the probability that you will receive no calls is .1.

a. Verify that the "Conditions for Probabilities for Discrete Random Variables" given on page 267 are met.

b. Draw a picture of the probability distribution function.

c. Write a table that gives the cumulative probability distribution for X.
