If A and B are mutually exclusive events with P(A) = 0.70, then P(B)：（ ）
举一反三
- If A and B are mutually exclusive events with P(A) = 0.70, then P(B)：（ ） A: can take any value between 0 and 0.70 B: cannot be determined from the information given C: cannot be larger than 0.30 D: can take any value between 0 and 1
- 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 two events are mutually exclusive, they have no outcomes in common.
- The intersection of two mutually exclusive events must always be equal to 0.
