Let fx(2) be the probability density function of the random variable X. f(x) Le 2 0 <2<4; otherwise. 9 Find the variance of X. 0.88: (The answer should be a number rounded to five decimal places, don't use symbols such as %] The joint probability density function of two random variables X and Y is given by fxy(x,y) = SK 0<y <x<3.3; 10, otherwise. Find K so that fx.x(x, y) is a valid joint pdf. [The answer should be a number rounded to five decimal places, don't use symbols such as %]
