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.

Q. 1 It is estimated that 70% of emails are spam emails. Some software has been applied to filter these spam emails before they reach our inbox. A certain brand of software claims that it can detect 99% of spam emails, and the probability for a false positive (a non-spam email detected as spam) is 5%. Now if an email is detected as spam, then what is the probability that it is in fact a non-spam email?
