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?
To find the probability of winning money, we must first determine the probability of winning candy or pencils and then subtract that from 1.
The probability of winning candy is 3/5 and the probability of winning pencils is 3/10. So the probability of winning either candy or pencils is:
3/5 + 3/10 = 6/10 + 3/10 = 9/10
Therefore, the probability of winning money is:
1 - 9/10 = 1/10
So, the probability of winning money is 1/10.
