Part 2

For each situation, identify the sample size n, the probability of success p, and the number of successes x. When asked for the probability, state the answer in the form b(n,p,x). There is no need to give the numerical value of the probability. Assume the
conditions for a binomial experiment are satisfied. Complete parts (a) and (b) below.
C
a. In 2016, 15% of adults in a region smoked cigarettes. If 25 adults from this region are randomly selected, what is the probability that exactly 7 are smokers? Let a success be an adult that is a smoker.
The probability is b(n,p,x)=b (25, 0.15,7)
(Type integers or decimals. Do not round.)
