When customers enter a store there are three outcomes that can occur: buy nothing, buy a small amount, or buy a large amount. In this situation if a customer buys a large amount, he or she cannot also buy a small amount or buy nothing. Given this information, we can conclude that these events constitute:A) all inclusive.
B) mutually exclusive.
C) dependent events.
D) independent.

The correct answer is B

Explanation:

Mutually exclusive is the term of statistics which is defined the events, that occur two or more times but cannot coincide. In short, it is stated as the situation or circumstance where the occurrence of the one result or outcome supersedes the other outcome or this event means that the outcomes cannot happen at the same time.

So, in this case, when the customer visit the store, either purchase large amount of quantity, small amount of quantity or nothing. Therefore, these events are constitute as mutually exclusive.
