What is the probability formula for "at least one of A or B should occur"?

• P(A) + P(B)

• P(A) + P(B) + P(A ∩ B)

• P(A) + P(B) - P(A ∩ B)

• P(A ∩ B)

Which formula represents the probability that exactly one of events A or B occurs?

• P(A) + P(B) - P(A ∩ B)

• P(A) + P(B)

• P(A ∪ B) - P(A ∩ B)

• P(A ∩ B)

What is the probability formula for "neither A nor B occurs"?

• P(A ∪ B)

• 1 - P(A ∪ B)

• P(A ∩ B)

• 1 - P(A ∩ B)
