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.
find the indicated probability.
