we are given two probabilities of two events: P(A) = 0.25, and P(B) = 0.45. we are asked to determine P(A ∩ B) which has a formula of P(A) * P(B) equal to 0.25 *0.45 equal to 0.1125. P(A ∪ B) has a formula of P(A) + P(B) equal to 0.70. (c) P(A | B) is 0.25/0.45 equal to 0.56. (d) P(Ac ∪ Bc) is equal to (1-0.25)*(1-0.45) equal to 0.4125.
