Given two events, A and B, if the probability of A is 0.7, the probability of B is 0.3, and the joint probability of A and B is 0.21, then the two events are independent?Select one:a.True.b.False.

Given P(A) = 0.9 and P(B) = 0.3, do the following.(a) If A and B are independent events, compute P(A and B).(b) If P(A | B) = 0.6, compute P(A and B).Step 1(a) If A and B are independent events, 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.Recall that two events are independent if the occurrence or nonoccurrence of one event does not change the probability that the other event will occur.We are given that A and B are independent events, so we can use the multiplication rule for independent events. It is also given that P(A) = 0.9 and P(B) = 0.3.P(A and B)  =  P(A) · P(B) =  (0.9) ·    =

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

If P(A) = 0.70 and P(B) = 0.20, then A and B are independent events if _____.A.P(A or B) = 0.14B.P(A and B) = 0C.P(A and B) = 0.14D.P(A or B) = 0.90SUBMITarrow_backPREVIOUS

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.
