1. In 1881, Simon Newcomb discovered that digits do not occur with equal frequency. After studying lots of data, he assigned probabilities for each of the first digits of numbers. This is known as Benford’s Law (because a physicist named Frank Benford proved it at a later date) and plays a major role in identifying tax fraud. Digit Probability1 0.3012 0.1763 0.1254 0.0975 0.0796 0.0677 0.0588 0.0519 0.046 A.) Verify that this is a probability model.B.) Use Benford’s Law to determine the probability that a randomly selected first digit is 1 or 2.C.) Use Benford’s Law to determine the probability that a randomly selected first digit is at least 6.2.
