7. A marble is selected at random from a jar containing 10 red marbles, 70 yellow marbles, and 20
green marbles. Find the theoretical probability that it is either red or green.
8. In a class of 148 students, 94 are taking math (M), 77 are taking science (S), and 52 are taking both
math and science. One student is picked at random. Find the probability that the student is taking
math or science or both.
9. A pet store has 10 puppies, including 5 poodles, 2 terriers, and 3 retrievers. If Rebecka selects one
puppy at random, the pet store replaces the puppy with a puppy of the same breed, and then Aaron
chooses a puppy at random. Find the probability that they both select a poodle.
