It is often easier to separately find the output noise for each noise source in separately and then add them by superposition. Then, the mean squared output noise is the sum of the squares of all the separate noise sources. The average noise that you would measure on the output is the square root of the mean-squared output noise. This is what you compare with the signal on the output to get the signal to noise ratio.
