Question

Q.2 The American Journal of Public Health (July 1995)
published a study of the relationship between passive smoking and
nasal allergies in Japanese female students. The study revealed
that 40% of the students from heavy-smoking families showed signs
of nasal allergies on physical examination. Let x denote the number
of students with nasal allergies in a random sample of 6 Japanese
female students exposed daily to heavy smoking.

a. What is the probability that at least four of the students will
have nasal allergies?

b. What is the probability that at least two of the students will
have no nasal allergies?

c. Suppose instead of 6, a random sample of 20 Japanese female
students were exposed daily to heavy smoking, what is the
probability that between 4 and 14 (both points inclusive) of the
students will have nasal allergies?
