Question

Events A and B are mutually exclusive, with P(A) = 0.36 and P(B) = 0.05. 

What is P(A or B)?

  A.

0.018   B. 0.31   C. 0.41   D. 0.86

Answer 1

Since A an B are mutually exclusive, you can just add the two probabilities. Mutually exclusive means that one does not depend at all on the other.
