A pet store has 12 puppies, including 3 poodles, 5 terriers, and 4 retrievers. if rebecka and aaron, in that order, each se
lect one puppy at random without replacement, find the probability that aaron selects a retriever, given that rebecka selects a poodle.
1 answer:
Total number of puppies = 12
Where;
Poodles = 3
Terriers = 5
Retrievers = 4
After Rebecca selects a poodle, total number of puppies remaining = 12 -1 =11
Then,
Probability of Aaron selecting a retriever:
P(R) = Number of retrievers/New total = 4/11
