QuestionWhat must be true for the probability of a randomly selected person having blood type A to be $P(A)=\frac{1}{4}$? Is this true?

Studdy Solution
This means that in order for the probability of a randomly selected person having blood type A to be0.25, one out of every four people in the population must have blood type A.
Whether or not this is true would depend on the actual distribution of blood types in the population. According to the American Red Cross, the distribution of blood types in the U.S. is not evenly split among the four types, so it is unlikely that this condition is met. However, the distribution could be different in other populations.
