### CFA Practice Question

A box of candy contains three types of candy: dark chocolate (DC), white chocolate (WC), and peanut butter (PB). There are 24 pieces of candy in the box, 8 of each kind. All pieces are wrapped in the same material and there is no way of finding out what kind of candy one has until one unwraps the candy. An experiment consists of selecting pieces of candy randomly and identifying each piece. Once a piece of candy has been removed from the box, it is not put back in the box. Consider the following events: A, observing a chocolate piece, A=(WC,DC), and B, selecting four pieces of candy such that B=(PB,DC).

Which of the following statements is correct?
A. Events A and B are not mutually exclusive.
B. Events A and B are not exhaustive.
C. Events A and B may or may not be in the same sample space.
Explanation: Events A and B are not mutually exclusive. The two events are not mutually exclusive nor disjoint because they share common outcomes. The events A and B are exhaustive because they cover all possible outcomes. A and B are a subset of the same sample space.
