Given two independent continuous random variables X and Y with probability distributionfx(x) and fy (y) below, determine Fz(2), where Z = X+Y. Reminder: The questionis asking for a cumulative probability value not a probability density value. The plotsprovided have differing scale and may not be to scale.fx(x) = 1/4, 0
