Introduction:

Denote X as a number selected by the random number generator.

According to the description of the problem, it can be understood that the random number generator chooses the numbers discretely, such as, 14, 15, 16, …, 72, 73, and does not choose numbers such as 14.25, 17.9, etc.

Thus, X follows a discrete uniform distribution between 14 and 73.

Discrete uniform distribution:

Suppose a random variable, X is defined over the range [a, b], such that, X can take N possible distinct, equidistant values...
