Let the number of pennies = 4 and the number of dimes =1. Then the total coins is 5 and the probability of drawing a dime is 1/5. The answer is B

Since the ratio of pennies to dimes is 4 : 1, the simplest case would be that there are 4 pennies and 1 dime. The probability of selecting a dime is 1/(1 + 4) = 1/5.

Answer: B
