Webb16 jan. 2024 · Answer: x = x i i = 1 k. The probability distribution of a discrete random variable x is described by a list of probabilities associated with each of its possible values x i. Also for the discrete random variable x with the expression P ( x) we say probability that the event x is true. In here P is pmf (probability mass function). The best example for understanding probability is flipping a coin: There are two possible outcomes—heads or tails. What’s the probability of the coin landing on Heads? We can find out using the equation P (H) = ? P (H) =? . You might intuitively know that the likelihood is half/half, or 50%. But how do we work that out?
