Individuals with Type A blood can receive blood from those with Type A or O; Type B, those with Type B or O; Type AB, those with any type; and Type O, only those with Type O. What is the sample space of blood types of one person? Your professor has Type A blood. From which blood types can he safely receive blood? In the United States, 42% of the people have Type A blood; 11% have Type B; 3% have Type AB; and 44% have Type O blood. What is the probability that a random citizen of the United States will be able to donate blood to your professor? Dr. Forsberg fell ill in Mumbai, India, and he needs a blood transfusion. The distribution of blood types in Mumbai is Type A: 29%; Type B: 28%; Type AB: 11%; and Type O: 32%. What is the probability that Dr. Forsberg can safely receive blood from a random person in Mumbai?
Explanation / Answer
In the ABO system, there are just four blood types: A, B, AB, and O. Individuals with Type A blood can receive blood from those with Type A or O; Type B, those with Type B or O; Type AB, those with any type; and Type O, only those with Type O. What is the sample space of blood types of one person? (A, B, AB, O) Your professor has Type A blood. From which blood types can he safely receive blood? O and A In the United States, 42% of the people have Type A blood; 11% have Type B; 3% have Type AB; and 44% have Type O blood. What is the probability that a random citizen of the United States will be able to donate blood to your professor? P(Type O or A) = .44 + 42 = .86 While vacationing in Mumbai, the professor fell ill. He needs a blood transfusion. The distribution of blood types in Mumbai is Type A: 29%; Type B: 28%; Type AB: 11%; and Type O: 32%. What is the probability that the professor can safely receive blood from a random person in Mumbai? P(type O or A) = .29 + .32 = .61
