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 the result to two decimal places.

Correct answer:

P =  0.5

Step-by-step explanation:

PA=0.53 PB=0.15 PAB=0.18  P=PA+PBPAB=0.53+0.150.18=0.5
