1. Five students in a statistics class of 400 students were chosen randomly to pick their grades from a hat (wouldn't we be so lucky). In the hat there are 65 grades: 13 A's13 B's, 13 C's, 13 D's and 13 F^ prime S . What is the probability that at least one of the 5 students gets an A?

2. 45% of planted flowers receive fertilizer. If the flowers receive fertilizer, they grow to their full heightIf they do not receive fertilizer, there is only a 20% chance of growing to their full height. You see a planted flower that has grown to its full height. What is the probability that it received fertilizer?
