If P(A and B. = 0, then A and B must be mutually exclusive.
举一反三
- If A and B are mutually exclusive events with P(A) = 0.70, then P(B)：（ ）
- The intersection of two mutually exclusive events must always be equal to 0.
- When A and B are mutually exclusive, P(A or B) can be found by adding P(A) and P(B).
- When A and B are mutually exclusive, P(A or B) can be found by adding P(A) and P(B). A: 正确 B: 错误
- If A and B cannot occur at the same time the events are called mutually exclusive.
