Montréal. Suppose a letter sent from Vancouver to Montréal has a probability of 0.75 of reaching Montréal within three (3) days. (a) What is the probability that exactly two (2) of the three (3) letters will reach Montréal within three (3) days? (b) What is the probability that at least one (1) of the three (3) letters will reach Montréal within three (3) days? (c) If the three (3) letters are mailed together at the same time and location, how does your conclusion in part (a) change?

The route used by a certain motorist in commuting to work contains two intersections with traffic signals. The probability that he must stop at the first signal is 0.45, the analogous probability for the second signal is 0.5, and the probability that he must stop at at least one of the two signals is 0.55. (a) What is the probability that he must stop at both signals? (b) What is the probability that he must stop at the first signal but not at the second one? (c) What is the probability that he must stop at exactly one signal?
A door-to-door salesman expects to make a sale 21% of the time when starting the day. But making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.32. If he makes no sale, the probability for a sale to the next customer stays at 0.21. What is the probability that he will make at least two sales with his first three visits?
A manufacturing process produces, on the average, 3% defective items. The company ships 15 items in each box and wishes to guarantee no more than 1 defective item per box. If this guarantee accompanies each box, what is the probability that the box will fail to satisfy the guarantee?
An airline claims that there is a 0.10 probability that a coach-class ticket holder who flies frequently will be upgraded to first class on any flight. This outcome is independent from flight to flight. Sam is a frequent flier who always purchases coach-class tickets. What is the probability that Sam’s first upgrade will occur after the third flight? What is the probability that Sam will be upgraded exactly 2 times in his next 20 flights? Sam will take 104 flights next year. Would you be surprised if Sam receives more than 20 upgrades to first class during the year? Justify your answer.
Suppose that historically, 35% of applicants that are offered admittance to Texas Tech actually enroll, while the others take offers somewhere else. If Texas Tech will accept 9000 this coming year, what is the probability that less than 34.1654% will actually enroll?
A door-to-door salesman expects to make a sale 14% of the time when starting the day. But making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.39.
