WebA probability function that specifies how the values of a variable are distributed is called the normal distribution. It is symmetric since most of the observations assemble around the central peak of the curve. The probabilities for values of the distribution are distant from the mean narrow off evenly in both directions. WebThe main limit theorem (CLT) is one of the most critical results the probability theory. It states so, under some conditions, the entirety of a bigger number of per variables is approximately normal. Here, wealth state a version of the CLT ensure applies to i.i.d. random variables. how to set up obs studio kreekcraft
