Question

Which of the following pairs of events, A and B, are disjoint? (a)A person is selected at random. A is the event “sex of the person selected is male” and B is the event “sex of the person selected is female.” (b)A person is selected at random. A is the event “the person selected earns more than $100,000 per year” and B is the event “the person selected earns more than $250,000 per year.”

          Which of the following pairs of events, A and B, are disjoint?
