Explanation:

Please consider the complete question.

The probability that a person in the United States has type O+ blood is 38%. Three unrelated people in the United States are selected at random. Find the probability that all three have type O+ blood.

Since the probability of having a O+ blood is an independent event, so to find probability that all three have type O+ blood we will use multiplication rule of independent events as:

`0.38* 0.38* 0.38=0.054872`

Therefore, the probability that all three have type O+ blood would be 0.054872.
