Select all that applyWhich of the following are key properties of the discrete probability distribution?Multiple select question.The probabilities of success and failure remain the same from trial to trialThe probability of each value x is a value between 0 and 1, or, equivalently, 0 ≤ P(X = x) ≤ 1The number of successes within a specified time or space interval equals any integer between zero and infinityThe sum of the probabilities equals 1. In other words, ΣP(X = xi) = 1, where the sum extends over all values x of X
