How do you calculate P(shaded number or number less than five)?

Back

Use the formula: P(A or B) = P(A) + P(B) - P(A and B). For example, 4/8 + 4/8 - 2/8.

Back

P(A or B) = P(A) + P(B) for mutually exclusive events.

Front

What is the formula for calculating the probability of mutually inclusive events?

Back

P(A or B) = P(A) + P(B) - P(A and B) for mutually inclusive events.
