Problem 1) Suppose that a cellular plan costs $20 per month with 30 minutes of use included and that each additional minute of use costs $0.50. If the number of minutes you use in a month is a geometric random variable M with an expected value of E[M] = 1/p = 30 minutes, what is the PMF of C, the cost of the plan for one month?
