The function p(x) is given by $${\text{p}}\left( {\text{x}} \right) = \frac{{\text{A}}}{{{{\text{x}}^\mu }}}$$   where A and μ are constants with μ > 1 and 1 ≤ x < $$\infty $$ and p(x) = 0 for $$ - \infty $$  < x < 1. For p(x) to be a probability density function, the value of A should be equal to

A. μ - 1

B. μ + 1

C. $$\frac{1}{{\left( {\mu - 1} \right)}}$$

D. $$\frac{1}{{\left( {\mu + 1} \right)}}$$

Answer: Option A
