How to tell if events are mutually exclusive?
Understand the Problem
The question is asking about the concept of mutually exclusive events in probability. It seeks to understand how one can determine whether two or more events do not occur at the same time. The response will likely explain characteristics of mutually exclusive events and provide criteria for identification.

More Information
Mutually exclusive events are also known as disjoint events. An example is flipping a coin, which can result in either heads or tails, but not both at the same time.
Tips
A common mistake is confusing mutually exclusive events with independent events. Mutually exclusive events cannot happen simultaneously, while independent events can occur at the same time but do not affect each other's probabilities.
