Answer:

0.054872

Step-by-step 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:

[tex]0.38\times 0.38\times 0.38=0.054872[/tex]

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