Question

a) 1 penny, 1 quarter, 1 dime
b) 1 penny, 1 quarter, 1 penny

Please show work. Thank You!

Answer 1

B) Is the answer.

Explanation:

If you have 15 quarters and 32 pennies, you have more than twice the amount of pennies that you do quarters. There is a small chance that it could be a dime or a nickel but this is unlikely. The chance of a quarter and penny falling out is much greater than a dime or nickle.
