Question

a pet store has 10 puppies, including 3 poodles, 5 terriers and 2 retrievers. if Rebecks selects 1 puppy at random, the pet store replaces the puppy with a puppy of the same breed, then aaron chooses a puppy at random. find the probability that they both select a poodle

Answer 1

There are 10 puppies total and 3 poodles, so the chance of Rebeck picking a poodle is 3/10. If that poodle is replace with a poodle, the chances of Aaron picking a poodle is also 3/10, 3/10x3/10=9/100, so the answer is 9/100 or 9%.
