Smoker male

For a person selected randomly from a certain population, events A and B are defined as follows. A = event the person is male B = event the person is a smoker. For this particular population, it is found that P(A ) = 0.53, P(B) = 0.15, and P(A n B ) = 0.18. Find P(A U B ). Round result to two decimal places.

Correct answer:

P =  0.5

Step-by-step explanation:

$$\begin{gathered} PA=0.53 \\ PB=0.15 \\ PAB=0.18 \\ P=PA+PB-PAB=0.53+0.15-0.18=0.5 \end{gathered}$$
