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?

O A B AB Type Rh+ 59 53 12 6 Rh− 9 8 3 2 14. Blood Groups and Types If two people are selected, find the probability that they are both type Rh−. a. Assume that the selections are made with replacement. Are the events independent? b. Assume that the selections are made without replacement. Are the events independent? 22. Using Probabilities for Identifying Significant Events a. Find the probability of getting exactly 4 sleepwalkers among 5 adults. b....
Historically, the proportions of all Caucasians in the United States with blood phenotypes A, B, AB, and O are 0.41, 0.10, 0.04, and 0.45, respectively. To determine whether current population proportions still match these historical values, a random sample of 200 American Caucasians were selected, and their blood phenotypes were recorded. The observed numbers with each phenotype are given in the following table. 8817 13 2 (a) Is there sufficient evidence, at the 0.05 level of significance, to claim that...
