Question

Dexter has four different coins in his pocket. He randomly selects a coin from his pocket, replaces it, and selects another coin. What is the probability that both coins are dimes? Please select one answer.

Answer 1

Answer:

Step-by-step explanation:

So what is the probability of the selecting the first coin? There are total of 4 different coins, so the probability of getting a dime is 1 out of 4, then he replace it, then again the probability stays the same, he still has 1 out 4 chance of getting a dime. So then it's just 1/4*1/4=1/16 :)
