QUESTION 1 1. Blood Types: All human blood can be typed as ( O, A, B ) or ( A B ). The frequency of the occurrence of these blood types varies by ethnic and racial groups. (8pts) According to Stanford University's Blood Center, these are the probabilities of human blood types in the United States (the probability for type ( A ) has been omitted on purpose): egin{tabular}{|l|l|l|l|l|} hline Blood Type & 0 & A & B & AB \ hline Probability & 0.44 & ( ? ) & 0.10 & 0.04 \ hline end{tabular} a. A person in the United States is chosen at random. What is the probability of the person having blood type A? For this assignment, you will always round to the second decimal place. QUESTION 2 b. A person with type ( A ) can donate blood to a person with type ( A ) or ( A B ). A person with type ( B ) can donate blood to a person with type ( B ) or ( A B ). A person with type ( A B ) can donate blood to a person with type ( A B ) only. A person with type ( mathrm{O} ) blood can donate to anyone. What is the probability that a randomly chosen person cannot donate blood to everyone?
