Question

A die is rolled. Event A: rolling an even number. Event B: rolling a number less than 4. Should the intersection be subtracted when calculating P(A or B)?

Accepted Answer

Yes, because some outcomes are both even and less than 4.

Answer

No, because the intersection is always zero.

Answer

No, because the events are mutually exclusive.

Answer

Yes, because all outcomes are in both events.
