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?
