Since the probability that the number of sales is 2 or 3 is 0.50, it means that the probability of getting 2 sales (P(X=2)) plus the probability of getting 3 sales (P(X=3)) equals 0.50. Therefore, the given probability distribution must satisfy this condition. This is true for many probability distributions, so it is plausible that this is the case here. Therefore, the answer is A) True.
