    Please see the attached file.
    This is Binomial distribution

    P(r)= ncr p r * q n-r

    p = probability of hypertension= 0.15
    q=1-p= 0.85
    n= 17

    r=0,1,2,3 etc are number who have hypertension

    We can tabulate the values for r=0,1,2,3, ------,17
    (though it is not required for the problem. We need P(0), P(1), P(2), P(3) only

    n= 17
    p= 0.15
    q=1-p= 0.85
    P(r)= ncr p r * q n-r ...

    Solution Summary

    The solution calculates probability for hypertension using Binomial. Two or three patients with hypertension are examined.
