Which statements about a probability distribution are always true? The probability of an outcome is never 0. The expected value of a probability distribution is the mean of the distribution. The sum of the probabilities in a probability distribution is equal to 1. Values for for a discrete random variable X in a probability distribution are always positive. A probability distribution must have more than one outcome.
