The probability that a person in the United States has type B+ blood is 10%. 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 nothing. (Round to six decimal places as needed.) (b) Find the probability that none of the three have type B+ blood. The probability that none of the three have type B+ blood is nothing. (Round to three decimal places as needed.) (c) Find the probability that at least one of the three has type B+ blood. The probability that at least one of the three has type B+ blood is nothing. (Round to three decimal places as needed.) (d) Which of the events can be considered unusual? Explain. Select all that apply. A. None of these events are unusual. B. The event in part (b) is unusual because its probability is less than or equal to 0.05. C. The event in part (a) is unusual because its probability is less than or equal to 0.05. D. The event in part (c) is unusual because its probability is less than or equal to 0.05.
