1. the probability of passing a math this semester is 64%. what is the probability of NOT passing a math class this semester?

2. the probability of winning the lottery is 0.0024%. what is the probability of NOT winning the lottery?​

Answer 1

1. 36.00%
2. 99.9976%

Explanation:

Two mutually exclusive events that cover all possible events have a combined probability of 1.

1. If there is no middle ground—you either pass math or you don't—then the probability of not passing math this semester is 100% - 64% = 36%.

2. If there is no middle ground—you either win the lottery or you don't—then the probability of not winning the lottery is 100% - 0.0024% = 99.9976%.
