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.

What is the probability that a randomly selected data entry has a first digit greater than 7?

The probability will be "0.477".

According to the given data,

  • Probability of D1 = 0.301
  • Probability of D2 = 0.176

By adding the probabilities, we get

→ [tex]P (D \leq = 2) = 0.301+0.176[/tex]

                     [tex]= 0.477[/tex]

Thus the response above is appropriate.
