Question 457872: Assuming that, of all persons 17 years and over, half the males and a third of the females are classified as presently smoking cigarettes, find the probability that in a randomly selected group of 10 males and 15 females.
a. exactly 10 smoke (4 males, 6 females)
You can put this solution on YOUR website! s=smoker, n=nonsmoker
men: 210*s^4n^6 Where s=.5 and n=.5
=.2051
.
women: 5005*s^6*n^9 Where s=1/3 and n=2/3
=.1786
.
.2051*.1786=.0366 that 4 males and 6 females smoke.
