Hi. I would like to find out the probability distributions function of the sum of 5 independant random variables. They are a sum of errors: 1%, 1%, 0.1%, 0.1%, 1%.(adsbygoogle = window.adsbygoogle || []).push({});

I think this is the convolution of all these.

So the limits are +/- 3.2%

I know the convolution of 2 square pulses becomes a triangle, but i'm unsure about lots of them.

I was also reading the central limit theorem that says convolution of many random variables aproaches a normal distribution, but I don't know what the height or width of it would be.
