Q. If you add several normally distributed random numbers, the result is normally distributed, where the mean of the sum is the sum of the individual means, also the variance of the sum is the sum of the individual variances. (Remember which variance is the square of standard deviation.) This is a difficult result to prove mathematically, but it is easy to demonstrate with simulation. To do so, run a simulation where you add three normally distributed random numbers, each with mean 100 also standard deviation 10. Your single output variable should be the sum of these three numbers. Verify with RISK which the distribution of this output is approximately normal with mean 300 also variance 300.
