Two events are mutually exclusive if( ) A: the<br/>probability of their intersection is 1. B: they have no sample points in common. C: the<br/>probability of their intersection is 0.5. D: the<br/>probability of their union is 1 and they have no sample points in<br/>common.
- 2
If two events are mutually exclusive, they have no outcomes in common.
- 3
If A and B cannot occur at the same time the events are called mutually exclusive.
- 4
The intersection of two mutually exclusive events must always be equal to 0.
