• A. Two events are mutually exclusive if they cannot both occur.
• B. Two events are mutually exclusive if they can both occur.
• C. Two events are mutually exclusive if they should both occur.
• D. None of these

Answer 1

The correct option is A Two events are mutually exclusive if they cannot both occur.

Two events are said to be mutually exclusive or disjoint if they cannot both be true or they cannot both occur.

A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.

Thus $\left(A\right)$ is correct option.
