  1. To solve this problem you need to do as shown below.

    P(A or B) = P(A) + P(B) → _Write disjoint probability formula._
    = P(A)/(Total#) + P(B)/(Total#)
    = 48/162 + 78/162 → _Add._
    = 112/162 → _Simplify if possible._
    = 0.6914 → _Use a Calculator._

    So as you can see ↓
    the answer is 112/162 or 0.619
