Central limit theorem - Wikipedia

In probability theory, the central limit theorem (CLT) establishes that, in some situations, when independent random variables are added, their properly normalized sum tends toward a normal distribution (informally a "bell curve") even if the original variables themselves are not normally distributed. ... The earliest version of this theorem, that the normal distribution may be used ...
