Determine the required probability for binomial distribution.
Office Visits what is the age distribution of patients who make office visits to a doctor or nurse? The following table is based on information taken from the Medical Practice Characteristics section of the Statistical Abstract of the United States.

Suppose that you are a district manager of the health management organization (HMO) who is monitoring the office of a local doctor or nurse in general family practice. This morning the office you are monitoring has eight office visits on schedule. What is the probability that?
At least half the patients are under 15 years old? First, describe how this can be modelled as a binomial distribution with 8 trials, where success is visitor age is under 15 years old and the probability of success is 20 percent.
