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
A3/10
B1/10
C1/5
D1/20
The probability of winning candy is 3/5 and the probability of winning pencils is 3/10. Therefore, the total probability of winning candy or pencils is:
3/5 + 3/10 = 6/10 + 3/10 = 9/10
Since there are only 3 prizes, the probability of winning money is:
1 - 9/10 = 1/10
Therefore, the correct answer is B) 1/10.
