Independent and Dependent Probability Review

Front

What is independent probability?

Back

Independent probability refers to the likelihood of an event occurring that is not affected by the outcome of another event.

Front

What is dependent probability?

Back

Dependent probability refers to the likelihood of an event occurring that is affected by the outcome of a previous event.

What is the formula for calculating the probability of dependent events?

Back

P(A and B) = P(A) * P(B|A), where P(B|A) is the probability of B given A.
