Medical records indicate that 40% of the people have type O+ blood. What is the probability that of the next seven people donating blood that: (a) At least five have type 0+ blood? (b) At most one has type O+ blood? c) More than five do not have type O+ blood?
4) There are four blood types (A, B, AB, and O) and two Rh factors +or -). Each person has a blood type and an Rh factor. The percentages of blood types and Rh factors have a strong relationship to ethnicityas we can see in the tables below US Pop Euro. Afr. L.

People with type O‑negative blood are known as universal donors. That is, a patient with any blood type can receive a transfusion of O‑negative blood. Approximately 7.6% of the American population has O‑negative blood. Suppose 8 people appear at random to give blood. Let A represent the event where at least one of the 8 people has type O‑negative blood. Calculate P(A), the probability that at least one of the 8 people has type O‑negative blood. Please round your answer...
Universal blood donors. People with type O-negative blood are referred to as universal donors, although if you give type O-negative blood to any patient you 13.28 run the risk of a transfusion reaction due tain antibodies present in the blood. Howe patient can receive a transfusion of O-ne blood cells. Only 7.2% of the American population have O-negative blood. If 10 people appear at ran- dom to give blood, what is the probability that at least one of them is...
. 40% of the population has type A blood. a. If 9 people are selected at random, what is the probability that less than four of them have type A blood. b. If 90 donors come to give blood one day, what is the probability that less than 40 of them have Type A blood (using the normal approximation)? Explain why this is higher or lower than the answer in part (a). c. If 15 people give blood one day,...
An individual's ABO blood type can always be determined by an analysis of the blood. About 80% of the people in North America are known as secretors, in which the ABO type is also secreted into other body fluids such as saliva. About 20% of North Americans are non-secretors, so their saliva always appears to be type O, no matter their actual ABO blood type. Non-secreting is a recessive treat. The ABO locus on chromosome 9, while the secretor locus...
A random blood bank has either type A, type B, or type O with probabilities 0.10, 0.35, 0.25. There is a 0.30 probability that the patient will need type AB. a) What is the probability that among 10 candidates needing blood, 5 need AB, 3 need A, and at least one needs O? b) What is the probability that the 6th candidate approaching for blood is the 3rd one needing B?
People with blood type O- are sometimes referred to universal donors as their blood can be used for all recipients. About 9% of the Australian population have blood type 0-. Suppose blood donors have the same distribution of blood types as the Australian population. In any 10 donors chosen at random, what is the probability that exactly 3 will have O- blood? In any 10 donors chosen at random, what is the probability that between 1 and 4 inclusive will...
If the probability of being blood-type A is 1/8 and the probability of blood-type O is %, what is the probability of being either blood-type A or O?
Of the four different blood types (O, A, B, AB), 43.4 percent of people have type O blood, 40.7 percent have type A blood, and 10.5 percent have type B. What percentage of people have type AB blood? Answer:
