Answer Choices:
- A) The union of two events includes all outcomes that are in either event.
- B) The intersection of two events includes only outcomes that are in both events.
- C) The complement of an event includes all outcomes that are not in the event.
- D) The intersection of two events includes all outcomes that are in either of the events.
- E) The union of two events includes only outcomes that are in both events.
✅ Answer:
The union of two events includes all outcomes that are in either event.; The intersection of two events includes only outcomes that are in both events.; The complement of an event includes all outcomes that are not in the event.
💡 Explanation:
In probability, the union of two events A and B (written as A ∪ B) includes all outcomes that are in either A, B, or both.
The intersection of two events A and B (written as A ∩ B) includes only the outcomes that are in both A and B.
The complement of an event A includes all outcomes in the sample space that are not in A.
