Question: the following is a probability distribution for a discrete random variable x?
Answer: The probability distribution of a discrete random variable X is a list of each possible value of X together with the probability that X takes that value in one trial of the experiment. ... Each probability P(x) must be between 0 and 1: 0≤P(x)≤1. The sum of all the possible probabilities is 1: ∑P(x)=1.
