Question

3 of the digits 0-9 are chosen randomly by a computer what is the probability that it will choose 3 sequential digits?

Answer 1

I will assume it has to pick 3 different digits.
There are C(10,3) = 120 combinations of 3 digits.
The only groups that are sequential of those 120 are:
012, 123, 234, 345, 456, 567, 678, 789.....8 combinations

8 / 120 = 0.0667

Answer 2

These are the answer choices. They are fractions
A.1/120


B. 1/15


C.1/20


D. 1/5040

Answer 3

8/120 simplifies to 1/15
