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

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

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

A blood bank asserts that a person with type O blood and a negative Rh factor (Rh−) can donate blood to any person with any blood type. Their data show that 41% of people have type O blood and 15% of people have Rh− factor; 47% of people have type O or Rh− factor.Part (a)Find the probability that a person has both type O blood and the Rh− factor.Part (b)Find the probability that a person does NOT have both type O blood and the Rh− factor.

A person can have one of the four blood types A, B, AB, and O. The proportions of the four blood types in a given population are(0.2, 0.3, 0.25, 0.25) respectively. Suppose the likelihood of a certain disease X in a person depends on the person's blood type as follows: A: 0.1, B: 0.1, AB: 0.2, and O: 0.4. a) What is the probability of disease X in a person chosen uniformly at random from the population? b) Knowing that the selected person has disease X, what is the probability that their blood type is A?

Two parents each have blood type AB, and their first child is blood type AB. What is the probability that their second child will have blood type AB? (Express the probability as a percent. Enter the number only without the percent sign. For example, enter 100% as 100 and enter 12.5% as 12.5.)
