Q2. A random variable X takes values between –2 and 3 with a probability density function x -25x50 f(x)=64 cx, 0<x<3 (a) Find the value of c and sketch the probability density function, hence determine P(-1 < X < 1) (b) Construct and sketch the cumulative distribution function. (c) Find the first and the second quartile of the random variable X.
