Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

How do you calculate the probability of an event?

Back

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Back

The probability is 3/4.

Front

What does P(not A) represent in probability?

Back

P(not A) represents the probability that event A does not occur.
