Question
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
Solution
The question is asking for the probability of a person having blood type A. However, the probabilities for blood types O, B, and AB are not provided in the question.
In general, the sum of all probabilities in a probability distribution is equal to 1. Therefore, if we know the probabilities of the other three blood types, we can subtract these from 1 to find the probability of blood type A.
Let's denote the probabilities of blood types O, B, and AB as P(O), P(B), and P(AB) respectively. The probability of blood type A, P(A), can be calculated as follows:
P(A) = 1 - P(O) - P(B) - P(AB)
Without the specific probabilities for blood types O, B, and AB, we cannot calculate the exact probability of blood type A. Please provide the probabilities for these blood types.
