Step-by-step explanation:
Let X be the number of persons out of 12 who have RH negative blood.
X is binomial since each person is independent of the other to have Rh negative blood.
n =12
a) What is the probability that exactly 5 of those patients will have Rh negative blood?
P(X=5) =
b) What is the probability that at least 3 of them will have Rh negative blood?
=0.6397
c) What are the expected number and standard deviation of the number of these patients with Rh negative blood?
E(X) = np = 
Var(x) = npq = 
Std dev =
