Explanation of Solution

Given information: Statement- “When an outcome falls outside the sample space, it is a failure”

Explanation-

A sample space is the set of all possible outcomes. No outcome can ever fall out of the sample space. An event is a failure when the outcome is part of sample space, but not a favorable outcome.

Consider example of coin flip. The outcome can only be heads or tails. If heads is favorable, then tails is not favorable, but it will always be in the sample space as it is a possible outcome.
