Outcome

Definition

Let $\Omega$ be a sample space of a random experiment. An outcome of the experiment is an element $\omega$ of $\Omega$.

Remarks

Two different outcomes cannot both happen in one trial. An outcome $\omega$ gives the event $\{\omega\}$, an elementary event. An outcome and an event are different things: an event is a set of outcomes. For a roll of a die, the outcomes are $1, 2, 3, 4, 5, 6$, and "the result is even" is the event $\{2, 4, 6\}$, not an outcome.

Explanations

L1 human

An outcome is one thing that can happen. When you toss two coins, "heads then tails" is one outcome, and there are four outcomes in total.
