odd or even

Number classification question

Odd or even is a simple game of chance where one player guesses whether a hidden quantity—usually fingers held up behind the back—will be odd or even.

The game resolves minor disputes or makes random selections: Let's play odd or even to see who goes first.

The phrase also describes any situation with roughly equal odds.
