The probability that he will pull out a nickel, then a quarter, then a nickel is
<u>Explanation:</u>
Given:
Number of dimes = 3
Number of Quarters = 2
Number of pennies = 2
Number of Nickles = 5
Total coins = 3 + 2 + 2 + 5
= 12
Probability that Armando will pull out Nickel first =
After taking out Nickel, the total number of coins in the pocket will be 11
So,
Probability that he will pull a quarter =
Total coins remaining = 11 - 1 = 10
Total Nickel remaining = 5 - 1 = 4
Probability that he will take our Nickel =
Total probability =
=
