An experiment consists of removing one card from a deck of 52 cards. Let S = (H,D,C,P). Let event A be the event in which the card removed is a heart (H) or a diamond (D), A= (H,D). Let event B be the event in which the card removed is a spade (P) or a club (C), B = (C,P). Which of the following statements is incorrect?

B. A and B are exhaustive events.

C. (D,C) is not a subset of S.

A. A and B are disjoint events.

B. A and B are exhaustive events.

C. (D,C) is not a subset of S.

Correct Answer: C

Although (D,C) is not defined as an event, it is a subset of S.

what is a disjoint event? |

Why is B not correct? |

B is correct! Lesson: Read Carefully. "Which of the following statements is INCORRECT?" If two events have no outcomes in common they are said to be disjoint events. |

Disjoint events have no outcomes in common. In this case that is true. |

disjoint=mutually exclusive=>P(A*B)=0 |
