Question 1175050: Suppose that in a certain malarias area past experience indicates that the probability of a person with a higher fever will be positive for malaria is 0.7. Consider 3 randomly selected patients (with high fever) in that same area.
a. What is the probability that no patient will be positive for malaria?
b. What is the probability that all patients will be positive for malaria?
c. Find the μ and SD. for this probability distribution.

This would be 0.3^3=0.027
For all, it would 0.7^3=0.343
mean is np=2.1 people
variance is np(1-p)=0.63 people^2
sd is sqrt (V)=0.79 people
