Formula for no of reflexive relation
WebSay A = {1, 2, ....... n −1, n } out of n 2 elements n elements are compulsory for relation to be reflexive. i.e (1, 1) (2, 2) (3, 3) .... (n, n) and for remaining n 2 − n elements, we have choice of filling i.e either they are present or absent. Hence, Total number of reflexive relation are 2 n 2 - n. Suggest Corrections 13 Similar questions Q. WebFor in general, by the Binomial Theorem, ( 1 + x) m = ∑ i = 0 m ( m i) x i. Put m = n 2 − n and x = 1.
