What does the probability of an event represent?

Back

The probability of an event represents the likelihood of that event occurring, expressed as a number between 0 (impossible) and 1 (certain).

How do you calculate the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is the complement of an event in probability?

Back

The complement of an event is the probability that the event does not occur, calculated as 1 minus the probability of the event.
