Consider that you have three dices. Now use indicator random variables to calculate the expected value of if the roll results in same number on each dice face. [E. G. All dices show six on the roll].

For a process taking place in a closed system containing gas, the volume and pressure relationship is pvi-constant. -1.5 bar, the process starts with initial conditions, pi = =0.03 m3 and ends with final volume, v2-0.05 m3 determine the work done by the gas.
