To find the probability of winning money, we first need to determine the probability of winning candy or pencils and then subtract that from 1.
Probability of winning candy = 3/5
Probability of winning pencils = 3/10
Total probability of winning candy or pencils = 3/5 + 3/10 = 6/10 + 3/10 = 9/10
Probability of winning money = 1 - Probability of winning candy or pencils
= 1 - 9/10
= 1/10
Therefore, the probability of winning money is 1/10.
Mrs. Johnson gives out prizes to her students who are good in class. Kids draw for a chance to win 3 prizes. They can win candy, pencils, or
.money. There is a 3/5 chance to win candy, and a 3/10 chance to win pencils. What is the probability of winning money?
