For this problem, assume that Pr[A ∪B] = 0.6 and Pr[A] = 0.35.(1) What is Pr[B] if A and B are independent events? (2) What is Pr[B] if A and B are disjoint events?

independent events E and F in a sample space S, but assume that Pr[E] = 0.4 and Pr[F] = 0.15. Compute the following conditional probabilities: (1) Pr[E′| F] = (2) Pr[E | F′] =

Assume that your sample space is S = { O1, O2, O3, O4, O5 } with associated weights (probabilities) w1 = 0.15, w2 = 0.30, w3 = 0.20, w4 = 0.10, and w5 = 0.25. Determine the probability of the... more
