Create Free AccountProbability measures how likely an event is to occur. It's a number between 0 and 1, where 0 means impossible and 1 means certain. You calculate it as: favorable outcomes divided by total possible outcomes.
To find probability: P(event) = favorable outcomes ÷ total outcomes. For example, the probability of rolling a 3 on a fair die is 1/6 because there's 1 favorable outcome (rolling 3) out of 6 total possible outcomes.
