1.0 There are two traffic lights on the route used by a certain individual to go from home to work. Let E denote the event that the individual must stop at the first light, second light. Supposed the P(E) = .4, P(F) = .3 and P(E∩F) = .15. a. What is the probability that the individual must stop at at least one light; that is, what is the probability of the event E U F? b. What is the probability that the individual needn’t stop at either light? c. What is the probability that the individual must stop at exactly pone of the two lights? d. What is the probability that the individual must stop event related to P(E) and P(E∩F)?

Suppose an airline found that about 7% of the people making reservations on a flight from Miami to Denver do not show up for the flight. Suppose that the airline overbooks this flight by selling 226 ticket reservations for an airplane with only 219 seats. Let n = 226 represent the number of ticket reservations. Let r represent the number of people with reservations who show up for the flight. Which expression represents the probability that a seat will be available for everyone who shows up holding a reservation: Expression I : P(r ≥ 226) Expression II : P(r ≥ 219) Expression III : P(r ≤ 226) Expression IV : P(r ≤ 219) Expression V : P(r = 219) a. Expression II b. Expression III c. Expression I d. Expression V e. Expression IV

A class contains 40 students. The probability of failing in one of the courses for each student is 0.03, but there is no chance to fail in more than one course. You know that a student failed in a course, the probability that the fail reason in non-attendance is 0.04. All other fail reasons are low average. The examinations are private, so the results are mutually independent. Let X and Y be the numbers of failed students due to non-attendance and due to low average, respectively, in that class this semester. Find the joint MGF

A study of the incoming freshman class at a university found that 60% of the students had taken AP Calculus in high school, 55% had taken AP English in high school, and 20% had taken both AP Calculus and AP English. One incoming freshman is randomly selected from the population of incoming freshman. Let: C = the selected student took AP Calculus E = the selected student took AP English What is the probability that the selected incoming freshman took AP English or AP Calculus, i.e. P( C or E)? 0.15 O 0.75 0.80 0.05 0.95
