Definition
Mutually Exclusive refers to a condition in probability and statistics in which two or more events cannot occur at the same time. If one event occurs, the other(s) cannot. Think of it as a tightrope walk: if you veer left, you’re likely to topple off!
Key Points:
- Events are mutually exclusive when the occurrence of one event inhibits the occurrence of another.
- Common in business scenarios, particularly regarding project selection and budgeting where choosing one option means giving up another.
Example
Imagine you’re deciding between an extravagant vacation or a new sports car. If you fund one, the other has to wave goodbye forever—aka, mutually exclusive decisions!
