What's the probability?

Question

At a local college, 51 of the male students are smokers and 459 are non-smokers. Of the female students, 60

are smokers and 540 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?

Answer 1

A - male smoker

B - female smoker

P(A) = number male smokers/total number male students

P(B) = number female smokers/total number female students

Since we are dealing with two independent samples:

P(A and B) = P(A) * P(B)
