This assignment is about K-map. There are some question in this form:Consider the function: f(A,B,C) = Σ m(1,3,7)

7.1) Which “little m” expression is correct for the complement of f(A,B,C)?

A. Σ m(0,2,4,5,6) B. Σ m(0,2,5,6) C. Σ m(1,3,7)
D. Σ m(0,1,2,4,7)

7.2) Which “big M” expression is correct for the complement of f(A,B,C)?A. ΠM(0,4,5,7)

B. ΠM(1,3)
C. ΠM(1,3,7)

D. ΠM(0,2,4,5,6)

Please help with this form.
