Question 1
Calculate the mean value of a function defined by $F(x) = x^2$ where x follows a uniform distribution between -1 and 1.
💡 Hint: Break the integral into parts and remember to apply the bounds of the uniform distribution.
Question 2
Find the mean of a function involving two variables, F(x, y) = xy, where x and y are independent random variables uniformly distributed over [0, 1].
💡 Hint: Carefully apply the integration in two dimensions by solving the inner integral first.
