Given the statement:
A pet store has 14 puppies, including 4 poodles, 5 terriers, and 5 retrievers. If Rebecka and Aaron, in that order, each select one puppy at random with replacement (they may both select the same one).
Find the probability that they select a poodle.
Solution:
Since it is stated that both of them will select the puppies, we simply need to divide the number of poodles by the number of puppies.
= 4 poodles/ 14 puppies
= 4/14
= 0.2857
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.2857)(100)
= 28.57%
Final answer:
= 28.57%
