Three electron emitters produce electron beams with changing kinetic energies that are uniformly distributed in the ranges [2,8], [2,8], and [5,6]. Let denote the total kinetic energy produced by these electron emitters. (a) Suppose that the three beam energies are independent. Determine the mean and variance of . Round your answers to two decimal places (e. g. 98.76).
