Blood Types The probability that a person in the United

Step 1 of 4

(a)

The probability that a person in the U.S. has type B+ blood is 9%.

Five unrelated people in the U.S. are selected at random.

We are asked to find the probability that all five have type B+ blood.

Using independence rule of probability, we can write the probability that all five have type B+ blood,

\(P(\text { All five })=0.09 \times 0.09 \times 0.09 \times 0.09 \times 0.09=0.000006\)

[since the probability that a person in the U.S. has type B+ blood is 9% or 0.09]

Hence the probability is \(0.000006 \text {. }\)
