Question

Quizplus · Accepted Answer

The probabilities in option B add up to 1 (10/80 + 23/80 + 37/80 + 10/80 = 80/80 = 1), indicating a valid probability distribution. Options A and C also add up to 1, but the presence of negative probabilities in option C makes it inaccurate. Option D cannot be chosen as it does not provide a valid option.
