If P(A | B) = 0.6, compute P(A and B).We are given that P(A | B) = 0.6 and P(A) = 0.9. Since P(A | B) ≠ P(A), the occurrence of event B changes the probability that event A will occur. This implies that A and B are events.So, to determine P(A and B), we can apply the general multiplication rule for events. Recall that P(B) = 0.3.P(A and B)  =  P(B) · P(A | B) =  (0.3) ·    =

Given P(A) = 0.3, P(B) = 0.5, P(A | B) = 0.3, do the following.(a) Compute P(A and B).(b) Compute P(A or B).Step 1(a) Compute P(A and B).To compute P(A and B) means that we wish to find the probability that both A happened and B happened. We are given that P(A) = 0.3, P(B) = 0.5, and P(A | B) = 0.3.Since P(A | B) ≠ P(A), the occurrence of event B the probability that event A will occur. This implies that A and B are not independent events.So, to determine P(A and B), we can apply the general multiplication rule for events.P(A and B)  =  P(B) · P(A | B) =  (0.5) ·    =
