I know what a normalization of numbers mean in probability. As far as I know; If a=3, b=2,c=1: Then nomalized value of a is 3/(1+2+3), b is 2/(1+2+3) & c is 1/(1+2+3).

But I dont know why do we take normalization and what are some of the applications of it.

Thanks some enlightment is appreciated.
