n 1938, a physicist named Frank Benford discovered that the number 1 appears in the first digit of random data more often than the number 2, the number 2 more often than the number 3 and so on. In general, the probability of occurrence of the first digit of a number can be written in he form of a probability function x + 1 P(X = x) = log X a. Prove it P(X= x) = log ) untuk x = 1,2,3,4...,9 x+1 X " x = 1,2,3,4..., 9 is a probability mass function b. Find the cumulative distribution function of X!
