SOLUTION: I go 0.50 for both .Am I on the right track? Please help thanks. The event A and B are mutually exclusive. Suppose P(A)=0.30 AND P(B)=0.20. (a) Find the probability of either A

Question 1098241: I go 0.50 for both .Am I on the right track? Please help thanks.
The event A and B are mutually exclusive. Suppose P(A)=0.30 AND P(B)=0.20.
(a) Find the probability of either A or B occurring.
(b)Find the probability that neither A or B will occur.

Yes, you are right. Either A or B occurring is 0.3+0.2-P(both), and P(both)=0, since they are mutually exclusive. The probability is 0.5
Neither A nor B will occur is also 0.5
