Question: All human blood can be "ABO-typed" as one of O, A, B or AB, but the probability distribution of the types varies a bit among

groups of people. The table below gives the distribution of blood types for a randomly chosen person in the United States.

Blood Type O A B AB
U.S. Probability 0.45 0.40 0.11 ?

  1. What is the probability that a randomly selected person in the US will have type AB blood?
  2. Maria has type B blood. She can safely receive transfusions from people with blood types O and B. What is the probability that a randomly chosen American can donate blood to Maria?
    Blood Type O A B AB
    China Probability 0.35 0.27 0.26 0.12
  3. Choose a US citizen and a citizen of China at random, independently of one another. What is
    the probability that both have type O blood ?
  4. Choose a US citizen and a citizen of China at random, independently of one another. What is
