Greater than probability
WebThe mathematical definition of a discrete probability function, p(x), is a function that satisfies the following properties. The probability that x can take a specific value is p(x). ... This means that the height of the probability function can in fact be greater than one. The property that the integral must equal one is equivalent to the ... WebAug 8, 2024 · This result represents p(Z < z), the probability that the random variable Z is less than the value Z (also known as the percentage of z-values that are less than the given z-value ). For example, suppose you want to find p(Z < 2.13). Using the z-table below, find the row for 2.1 and the column for 0.03.
