Problem 1: A random variable X whose probability density function is given by $$f_x(x) = 0.38\delta(x-2) + k \text{tri} \left(\frac{x-2}{3}\right).$$ Another random variable Y is related to X through Y = 2X-3. Find 1. The value of k 2. The expected value and the variance of X 3. The probability density function of Y.
