You can put this solution on YOUR website!
If youa re given information that P(A) = .30 and P(B)= .40, can you compute P(A or B)?
P(A or B) = P(A) + P(B) - P(A and B)
-----------------------------------------
If events A and B are mutually exclusive can you compute P(A or B? explain?
P(A or B) = P(A) + P(B) = 0.3 + 0.4 = 0.7
