Sir one doubt u put n1+n2-2 for unbiased variance formula so for biased one the denominator of the formula have to be n1+n2 right sir but u have put n1+n2-2 for both unbiased and biased why it so?

[@DrHarishGarg]

The capital "S" is know as Unbiased estimator of S.D. that why we divided by degree of freedom i.e., n1+n2-2 always
