Ответ:
25/196 = 0.128
Step-by-step explanation:
There are a total of 14 puppies, 5 of which are poodles.
The probability that Rebecka selects a poodle is 5/14.
Since the poodle is replaced, the probability that Aaron selects a poodle is also 5/14.
So the probability of both is (5/14) (5/14) = 25/196 = 0.128.
