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. A = event the person is male
B = event the person is a smoker For this particular population, it is found that $\mathrm { P } ( \mathrm { A } ) = 0.47 , \mathrm { P } ( \mathrm { B } ) = 0.31$ , and $\mathrm { P } ( \mathrm { A } \& \mathrm {~B} ) = 0.12$ . Find $\mathrm { P } ( \mathrm { A }$ or $\mathrm { B } )$ . Round approximations to two decimal places.

• A)\(0.90\)
• B) \(0.78\)
• C) \(0.54\)
• D) \(0.66\)
