The first digits of data entries in most real-world data sets are not uniformly distributed. The most common first digit is 1, followed by 2, and so on, with 9 being the least common first digit. This phenomenon is known as Benford's Law. The table below is the probability distribution for Benford's Law where the random variable D represents the first digit in a data entry. D P(D) D P(D) 1 0.301 6. 0.067 2 0.176 7 0.058 3 0.125 8. 0.051 4 0.097 9. 0.046 5 0.079 What is the probability that a randomly selected data entry has a first digit less than 4? P(first digit less than 4) =
