## 11.Suppose that you are a student worker in the statistics department and agree to be paid by the Random Pay system. Each week the Chair flips a coin. If the coin comes up heads, your pay for the week is \$80; if it comes up tails, your pay for the week is \$40. You work for the department for 100 weeks (at which point you have learned enough probability to know the system is not to your advantage). The probability that , your average earnings in the first two weeks, is greater than \$65 is a. 0.2500. b. 0.3333. c. 0.5000.
