Question

A change jar holds 36 nickels, 30 dimes, and 15 quarters. What is the probability that a nickel will be drawn first and then a dime (without replacement)?

A. 40/243
B. 22/27
C. 1/6
D. 1/12

Answer 1

36+30+15 = 81 total coins

36/81 reduces to 4/9 for a nickel

30/80 reduces to 3/8 for a dime

4/9 x 3/8 = 12/72 reduces to 1/6 probability
