A florist prepares bouquets for customers each day. For each bouquet, there is a 30% chance that it will include a specific rare flower. Find the probability that at most one bouquet out of five will include this rare flower. Enter the answer correct to two decimal places. Suppose person *A* makes accurate predictions about the weather with a probability of 4/7 and person *B* makes accurate predictions with a probability of 2/3. If you ask both of them their predictions about tomorrow’s weather, what is the probability that their predictions will be contradictory? Enter the answer correct to two decimal places. A box contains 10 red marbles, 8 blue marbles, and 12 green marbles. If one marble is drawn at random, what is the probability that it is either red or green? Enter the answer correct to two decimal places.
