Step 1
Since the probability is given as 40, we can assume it means 40%. So, the probability of a person having Type A blood is 0.40. Now, we want to find the probability that all 5 people have Type A blood. Since the blood types of the donors are independent events, we Show more…

The American Red Cross says that about 45% of the U.S. population has Type O blood, 40% Type A, 11% Type B, and the rest Type AB. a) Someone volunteers to give blood. What is the probability that this donor 1) has Type AB blood? 2) has Type A or Type B? 3) is not Type O? b) Among four potential donors, what is the probability that 1) all are Type O? 2) no one is Type AB? 3) they are not all Type A? 4) at least one person is Type B?
