8. There are four main blood types: A, B, AB, and O. A report is published that says that 40% of the United States population has Type A blood, 11% has Type B blood, 4% has Type AB blood, and the rest have Type O blood. Given what you know about probability and probability models, which of the following statements is correct? A. More than 50% of the United States population must have Type O blood. B. A person either has Type O blood or not, so the probability of having Type O blood is 0.50. c. If we randomly select one person from the United States population, there is a 29% chance that person will have either Type A or Type B blood. D. If we randomly select one person from the United States population, there is a 56% chance that person will have either Type B or Type O blood. E. Without knowing the total population size, it would be impossible to use this information to figure out the proportion of the United States population that has Туре О blood.
