The American College of Obstetricians and Gynecologists reports that 32% of all births in the United States take place by Caesarian section each year. Five woman are about to give birth.
What is the binomial probability that less than 3 will have a C-section birth?
0.0391
0.1906
0.9609
0.8095
Answer explanation
Binomial Probability Formula!
n = 5
p = 0.32
q = 1 - p = 0.68
x is "less than 3", so you have to find the probability when x is 2, 1 and 0. Then add them together.
p(0) = 0.1454
p(1) = 0.3421
p(2)=0.322
So, 0.1454 + 0.3421 + 0.322 = 0.8095
