# Question: A real number between 0 and l00 is randomly selected

A real number between 0 and l00 is randomly selected according to a uniform distribution and rounded off to the nearest integer. For example, 36.5001 is rounded off to 37; √3 is rounded off to 2; and 69.49 is rounded off to 69. Define a random variable to be X = (number selected)–(nearest integer).

(a) What is the domain of this random variable?

(b) Determine the PDF for X.

(c) Determine the mean square value of X.
