Find the indicated probability by using the general addition

Find the indicated probability by using the general addition rule. For a person selected randomly from a certain population, events A and B are defined as follows. For this particular population, it is found that P(A) = 0.52, P(B) = 0.33, and P(A & B) = 0.151. Find P(A or B). Round approximations to two decimal places.

Solution

We know that,

P(A or B) = P(A) + P(B) - P(A and B)

=0.52+0.33 - 0.151 = 0.699

so answer is C
