fifty-fifties

Coin flip chances

Fifty-fifties are situations with equal odds of two outcomes—a coin flip's chance.

The term appears in skiing and skateboarding for a grind where the board slides along an obstacle with weight distributed evenly across both trucks: He landed a clean fifty-fifty on the rail.

In everyday speech, fifty-fifties describe uncertain propositions: The surgery's success is fifty-fifties at best.
