P b 0.5 p a ∩ b 0.4. find p a b
SpletThe probabilities for A and for B are P(A) = 3 4 3 4 and P(B) = 1 4 1 4. Let C = the event of getting all heads. C = {HH}. Since B = {TT}, P (B ∩ C) = 0 P (B ∩ C) = 0. B and C are mutually exclusive. (B and C have no members in common because you cannot have all tails and all heads at the same time.) Let D = event of getting more than one ... SpletPROBABILITY THEORY 1. Prove that, if A and B are two events, then the probability that at least one of them will occur is given by P(A∪B)=P(A)+P(B)−P(A∩B). China plates that have been fired in a kiln have a probability P(C)= 1/10 of being cracked, a probability P(G)=1/10 of being imperfectly glazed and a probability P(C∩G)=1/50 or being both both cracked and
