# Binomial Distribution

Given: probability of hypertension is 0.15 What is the probability that out 3 out of 17 patients have hypertension:

at most 2 patients have hypertension

at least 3 patients have hypertension

#### Solution Preview

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.
