What is the sum of the different probabilities for a given event like flipping a coin or rolling a die?

Back

100%

Answer explanation

The sum of all the outcomes of an event MUST be 100%, because one of the possibilities must occur.

For example, when flipping a coin, heads is 50% likely and tails is 50% likely. 50% + 50% = 100%, which makes sense - when you flip the coin, one of those two things MUST happen.
