Here is the question:
Give minimal sum of products expressions for the following function F and for F(not)
F(A;B;C;D) = *sigma*(2; 3; 5; 6; 8; 9; 10); Fdc(A;B;C;D) = *sigma*(0; 12; 13; 14)

For 'F', all I did was create a Karnaugh map with 1's in the place of 2,3,5,6,8,9,10 and X's for 0,12,13,14.

I'm not sure what I am supposed to do to find the minimal sum of products for F(not). The way I did it was create another Karnaugh map with 1's in the place of 1,4,7,11 and X's again for 0,12,13,14. I got an answer, just wanted to make sure that if I invert the Karnaugh map, I will get the corrent F(not) minimal sum of products.
