Final answer:
To find the probability that a person is from Texas, given that they prefer brand A, we need conditional probability. However, the information provided does not allow us to determine the correct answer.
Step-by-step explanation:
To find the probability that the person is from Texas, given that the person prefers brand A, we need to use conditional probability. Let's denote P(T) as the probability that the person is from Texas, and P(A) as the probability that the person prefers brand A. The conditional probability formula is P(T|A) = P(T ∩ A) / P(A), where P(T ∩ A) is the probability that the person is from Texas and prefers brand A, and P(A) is the probability that the person prefers brand A.
Unfortunately, the information provided does not give us any data about the probability of a person being from Texas. Without this information, we cannot calculate the probability P(T|A) and determine the correct answer. Therefore, none of the given options (A, B, C, D) can be correct.
