In a sample of 50 people, 21 had type 0 blood, 22 had type A blood, 5 had type B blood, and 2 had type AB blood, find the  probability of  the following a.       A person had type O blood

200 people attended a blood bank and their blood types are recorded as follows: 50 have type A,65 have type B, 70 have type O and 15 have type AB.(a) Calculate the relative probability of each blood type.(b) If two people are selected without replacement, what is the probability that:(i) One person is type A and the other is type B.(ii) They both have type B blood.(iii) They both have the same type blood

Both parents have AB blood. What is the probability they will have a child that also has type AB blood?Group of answer choices25%75%0%50%100%

All human blood can be typed as one of O, A, B, or AB. The probability distribution varies a bit with race. If a person is randomly selected from a population, the approximate probabilities that the person selected will have a blood type O, B, or AB is shown in the table below. What is the probability that the person chosen has a blood type A?*1 point0.270.250.400.50

Blood type AB is the rarest blood type, occurring in only 4% of the population in the United States. In Australia, only 1.5% of the population has blood type AB. Suppose a random sample of 50 U.S. residents and 40 Australians is obtained. Consider the random variables described below:X: the number of U.S. residents with blood type ABY: the number of Australians with blood type ABWhat is the probability that exactly 2 of the U.S. residents have blood type AB?
