Now , We have $n$ variables so total number of combination possible is $2^{n}$. No it will be a neutral function if output of half these combination is 1 and half of these combination is 0 which implies no of Maxterm is equal to no of minterm. So we need half of the total combination means $2^{n-1}$ is Maxterm and rest $2^{n-1}$ is minterm. So this is same as selecting $2^{n-1}$ combination from total $2^{n}$ . So with $n$ variable total number of neutral function is $\binom{2^{n}}{2^{n-1}}$ 0 votes 0 votes Shubham Sharma 2 commented Aug 24, 2022 reply Follow Share Hopefully, you might get some insight about derivation from this video –> Watch from 1:03 till the end. 0 votes 0 votes Please log in or register to add a comment.
