Find the indicated probability.

If P (B) = 0.5, P (A or B) = 0.3, and P (A and B) = 0.6, find P (A) =

The events included here are non-mutually exclusive. this means the two have common elements that exist between them. The general addition rule that applies to the given data is as follows:

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

0.3 = P (A) + 0.5 - 0.6

P (A) = 0.4
