Medical records indicate that 40% of the people have type O+ blood. What is the probability...
It is known that 80% of people donating blood have a particular type of protein. Five people are randomly selected. 1 What is the probability that at least one person does not have the type of protein? 2 What is the probability that at most four have the type of protein? 3 What is the smallest number of people who must be selected if we want to be at least 90% certain that we obtain at least five people with...
. 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,...
Thirty-seven percent of the American population has blood type O+. What is the probability that at least four of the next five Americans tested will have blood type O+?
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...
People with type O-negative blood are universal donors whose blood can be safely given to anyone. Only 7.2% of the population have O-negative blood. A new, larger random sample was obtained involving 300 donors from the general population. What is the probability that more than 5% of the donors have O-negative blood? Question 3 options: A) 0.0708 B) 0 C) 0.9834 D) 0.9292 E) 0.0166
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...
A man with Type AB blood marries a woman with Type O blood. (With this in mind answer the next questions.) 40. C What is the probability that they will have a child with Type O blood? A. O B. 0.25 C. 0.5 D. 0.75 E. 1 41. _ What is the probability that they will have a child with Type A blood? (use answers from previous question)
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...

The blood groups of 200 people is distributed as follows: 50 have type A blood, 65 have B blood type, 70 have O blood type and 15 have type AB blood. If a person from this group is selected at random, what 5 is the probability that this person has O blood type?
