What is the formula for conditional probability?

Back

The formula for conditional probability is P(A|B) = P(A ∩ B) / P(B), where P(A|B) is the probability of event A given that event B has occurred.

What is the difference between independent and dependent events?

Back

How do you find the probability of the union of two events?

Back

The probability of the union of two events A and B is given by P(A ∪ B) = P(A) + P(B) - P(A ∩ B).

What is an experimental probability?

Back

Experimental probability is the probability determined by conducting an experiment and observing the outcomes, calculated as the number of times an event occurs divided by the total number of trials.

Front

What does P(A|B) mean in probability?

Back

P(A|B) denotes the probability of event A occurring given that event B has already occurred.

What is the complement of an event?

Back

The complement of an event A, denoted as A', is the event that A does not occur, and its probability is given by P(A') = 1 - P(A).
