Consider a continuous random variable X with the probability density function fX(x) = |x|/5 , – 1 ≤ x ≤ 3, zero elsewhere.
I need to find the cumulative distribution function of X, FX (x).
2. Homework Equations
The equation to find the cdf.
The Attempt at a Solution
FX(x) = ∫-1x -u/5 du + ∫-10 -u/5 du + ∫0x u/5 du
For some reason, my result is just a constant, but I can't figure out why my equation is wrong?
