We found that P(A and B) = 0.15. Since the probability that both events happen at the same time is not 0, it means that events A and B have some outcomes in common. Therefore, the events A and B are not mutually exclusive.To compute P(A or B) means that we wish to find the probability that either A happened or B happened. Since the events are not mutually exclusive, we can apply the general addition rule for events. Recall that P(A) = 0.3 and P(B) = 0.5.P(A or B)  =  P(A) + P(B) − P(A and B) =  0.3 + 0.5 −  =

It is known that P(A) = 0.3, P(B) = 0.65, P(A and B) = 0.15 and P(A or B) = 0.8. Given that A occurs, what is the probability that B also occurs

The event A has probability 0.13 of occurring; and the event B has probability 0.34 of occurring. Also it is known that P(A and B) = 0.1. Calculate P(A or B) to two decimal places.

A and B are mutually exclusive events. P(A) = 0.60 and P(B) = 0.30. What is P(A or B)?A.0.15B.0.90C.0.72D.0.18

Let A and B two independent events which are mutually exclusive. If P(A)=0.5 then P(B)=

Events A and B are mutually exclusive. Suppose event A occurs with probability 0.28 and event B occurs with probability 0.5.Compute the following.(If necessary, consult a list of formulas.)(a) Compute the probability that B occurs or A does not occur (or both).(b) Compute the probability that either B occurs without A occurring or A and B both occur.
