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?
Responses
A 3/10
B 1/10
C 1/5
D 1/20
B 1/10
Explanation:
Since the sum of the probabilities of winning candy and pencils is 3/5 + 3/10 = 6/10 = 3/5, the probability of winning money is 1 - 3/5 = 2/5. Since there are only 3 options, the probability of winning money is 2/5 divided by 3, which simplifies to 2/15 or 1/10.
