I am having a problem helping my daughter with her homework.

Question

Mildred has a bag of coins. The bag contains 10 dimes, 5 nickels, and 1 penny. She will randomly select 2 coins from the bag one at a time without replacement. What is the probability that Mildred will select a dime first and then a penny?

Answer 1

Total possibilities = 16

Probability of  a dime of the first draw is 10/16 = 5/8

Probability of  a penny on the second draw = 1/15

Probability of both = 5/8 * 1/15 = 1/24
