Since these events are mutually exclusive, we use the addition rule.Pr ≥  = P(3) + P  + P(5)

Use the binomial probability distribution table to find each of the needed probabilities. Then use the probabilities to find the final answer, correct to three decimal places.P(r  ≥  3)  =  P(3) + P(4) + P(5) =

If the event is "a number rolled on a six-sided dice is greater than 5", then the probability of the complementary event is what?

The table gives a set of outcomes and their probabilities. Let A be the event "the outcome is greater than 5". Let B be the event "the outcome is divisible by 5". Find P(A or B).Outcome Probability1 0.112 0.013 0.314 0.045 0.186 0.257 0.1

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

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 −  =
