Question: If X is a random variable with density function f (x) on A x B, the median of X is that number M

If X is a random variable with density function f (x) on A ≤ x ≤ B, the median of X is that number M such thatM A f(x) dx = -la 1 2

In other words, Pr (X ≤ M ) = 1/2.

Find the median of the random variable whose density function is f (x) = 2(x - 1), 1 ≤ x ≤ 2.

M A f(x) dx = -la 1 2
