n are said to be
mutually exclusive if the occurrence of any one them automatically implies the non-occurrence of the remaining
n-1 events. In other words, two mutually exclusive events cannot both occur.
Examples
- A flipped coin coming up heads and the same coin coming up tails are mutually exclusive events.
- A student passing a test and failing it are mutually exclusive (though someone can fail a test, retake it, and then pass).
