Probability
/prob-uh-BIL-ih-tee/
Definition
Probability measures how likely an event is to occur. It's calculated as the number of favorable outcomes divided by the total number of possible outcomes. Probability ranges from 0 (impossible) to 1 (certain).
💡Example
Rolling a 3 on a die: Probability = 1/6 ≈ 0.167 (one favorable outcome out of six possible). Flipping heads: Probability = 1/2 = 0.5 = 50%.
