Question

At a local college, 118 of the male students are smokers and 472 are non-smokers. Of the female students, 50 are smokers and 450 are non-smokers. A male student and a female student from the college are randomly selected for a survey. What is the probability that both are smokers? Do not round your answer.​

Answer 1

Answer:

The probability that both are smokers is 0.02

Step-by-step explanation:

Prob. of male smoker $P(ms)= \frac{118}{590} = 0.2$

Prob. of female smoker $P(fs) = \frac{50}{500} = 0.1$

Prob. that both ar smokers $P(bs)=P(ms) * P(fm) =0.2 * 0.1 = 0.02$
