The logic function y (a, B, c) = ab '+ a'B + (BC)' + BC is reduced to the simplest and non and the non expression "right and wrong" by formula method

The logic function y (a, B, c) = ab '+ a'B + (BC)' + BC is reduced to the simplest and non and the non expression "right and wrong" by formula method

Y(A,B,C)=AB'+A'B+(BC)'+BC //:(BC)'+BC=1
=AB'+A'B+1
=1
Therefore, the logical value of Y is equal to: 1;
That is: Y (a, B, c) = 1
