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
Please see the attached file.
This is Binomial distribution
P(r)= ncr p r * q n-r
p = probability of hypertension= 0.15
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
P(r)= ncr p r * q n-r ...
The solution calculates probability for hypertension using Binomial.
