The probability that a person in the United States has type B blood is 12%.
The probability that a person in the United States has type B blood is 12%. Three unrelated people in the United States are selected at random Complete parts (a) through (d).
(a) Find the probability that all three have type B blood
The probability that all three have type B blood is _______
Homework Answers
Given that
probability of person having B+ in United States will be = 0.12
Probability of having B+ for all 3 selected randomly will be = 0.12*0.12*0.12=0.001728
We have to multiply probability of 3 person because it will be independent event
