Derive the distribution of (X2 + X1-2)^2/(X2 - X1)^2. If the resulting distribution is one of the special distributions, identify the distribution and all relevant parameters; otherwise, state "unknown".Find the variance of the random variable X with a PDF given by 3x2 S* if - 1< x< 1, f(x) = 2 otherwise.
