Answer #1

Total number of puppies = 13

Probability tha R selects a terrier = (Number of terrier Total number of puppies) =

Probability tha Aaron selects a retriever = (Number of retriever Total number of puppies) =

Since the selection is done with replacement so, the events R selects a terrier and Aaron selects a retriever are independent

So, probability that R selects a terrier and Aaron selects a retriever = = = 0.0947

Answer: The probability is or 0.0947
