b) Find the probability that in a random sample of 40 men, that between 20 and 25, inclusive, will not wash their hands after using a public restroom?
c) Find the probability that in a random sample of 40 men, that fewer than 35 will not wash their hands after using a public restroom?
d) Find the probability that in a random sample of 40 men, that at least 35 will not wash their hands after using a public restroom?
e) Find the probability that in a random sample of 40 men, that more than 30 will not wash their hands after using a public restroom?
