Does anyone know how to answer this?
In a clinical test of the drug Viagra, it was found that 4% of those in a placebo group experienced headaches.
a) Assuming that the same 4% rate applies to those taking Viagra, find the probability that among 8 Viagra users, 3 experience headaches.
b) Assuming that the same 4% rate applies to those taking Viagra, find the probability that among 8 randomly selected users of Viagra, all 8 experienced a headache.

Use the binomial distribution, with n=8, r=3 and p=.04, to calculate this probability.
