Which formula do you use when two events are mutually exclusive?

• P(A or B) = P(A) + P(B)

• P(A or B) = P(A) + P(B) - P(A and B)

• P(A and B) = P(A) * P(B)

• P (A and B) = P(A) * P(B|A)

Which formula do you use when two events are NOT mutually exclusive?

• P(A or B) = P(A) + P(B)

• P(A or B) = P(A) + P(B) - P(A and B)

• P(A and B) = P(A) * P(B)

• P (A and B) = P(A) * P(B|A)

Two events are mutually exclusive if:

• they cannot happen at the same time
• they can happen at the same time
