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

What is an independent event in probability?

Back

An independent event is an event whose outcome does not affect the outcome of another event.

Front

What is a dependent event in probability?

Back

A dependent event is an event whose outcome is affected by the outcome of another event.

Front

How do you calculate the probability of two independent events occurring?

Back

To find the probability of two independent events A and B occurring, multiply their probabilities: P(A and B) = P(A) * P(B).

Front

How do you calculate the probability of two dependent events occurring?

Back

To find the probability of two dependent events A and B occurring, multiply the probability of the first event by the conditional probability of the second event: P(A and B) = P(A) * P(B|A).
