Anew electronic system is under study. For one of the subsystem best mass estimates of the components of subsystem were estimated using Monte Carlo Model. The results are given in table. In each case they can be assumed to be normally distributed. An error value is given to allow a suitable margin to be determined.

Calculate the budget mass of the sub system.
