Question

Three of the 20 coins in Mischa’s piggy bank are pennies. Mischa shakes a coin out of her piggy bank. Which word BEST describes the likelihood of Mischa shaking out a penny?

Answer 1

0.15

Explanation:

3 of the 20 coins are pennies. Thus, the probability of shaking out a penny is 3/20, or 15/100, or 0.15.

Answer 2

3/20. Mischa can only shake out 20 coins. And three of them would be pennies. So the chance is 3/20
