b) Nakos has 4 quarters, 3 dimes, and 2 nickels in his pocket. Nakos randomly picks two coins out of his pocket. What is the probability that he did not choose a dime either time, if he replaced the first coin before choosing a second coin?

OpenStudy (emmamink):

Well, find the probability of not picking a dime the first time. It would be 6/9, right? Now if he replaced the first coin before choosing again it would be 6/9.

OpenStudy (emmamink):

Now, multiply together and simplify.

OpenStudy (anonymous):

Wait multiply what together?

OpenStudy (emmamink):

6/9 by 6/9

OpenStudy (emmamink):

The probability of not choosing a dime either time
