Question

In the sickle cell anemia video that was shown during class it mentioned the following binomial probability distribution information:

X = number of children having sickle cell disease; (in this case x=3)

p = .25, probability of a child having the sickle cell disease when both parents are carriers of the disease

n = 6

In the probability distribution graph it showed that P(X = 3) is 0.132 or 13.2%. Use the binomial probability formula to verify the answer. Write down the formula and show your work and calculations.

Answer 1

This is a binomial distribution question with
n = 6
p = 0.25
q = 1 - p = 0.75
where
