Front

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

Back

P(A and B) = P(A) * P(B|A)

Front

What is the formula for the probability of two independent events?

Back

P(A and B) = P(A) * P(B)

Front

What is the formula for the probability of the union of two events?

Back

P(A or B) = P(A) + P(B) - P(A ∩ B)

Front

If the probability of an event occurring is 30%, what is the probability of it not occurring?

Back

Front

Define dependent events in probability.

Back

Dependent events are events where the outcome of one event affects the outcome of another.

Front

Define independent events in probability.

Back

Independent events are events where the outcome of one event does not affect the outcome of another.

Front

What is the complement of an event?

Back

The complement of an event A is the event that A does not occur, denoted as A'.

Front

How do you calculate the probability of the complement of an event?

Back

P(A') = 1 - P(A)
