Let A and B be two independent events. If P(B) = 0.5, what can you say about P(B | A)? Cannot find it because P(A) is not known. Cannot find it because P(B and A) is not known. Cannot find it because both P(A) and P(B and A) are not known. It is equal to 0.5. It is equal to 0.25.

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.

If two events A and B are independent and you know that P(A) = 0.35, what is the value of P(A | B)?

Suppose that the probability of event A is 0.2 and the probability of event B is 0.4. Also, suppose that the two events are independent. Then P(A|B) is:Question 16Select one:a.P(A)/P(B) = 0.2/0.4 = ½b.None of the above.c.P(A) = 0.2d.P(A) × P(B) = (0.2)(0.4) = 0.08

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) ·    =
