a) F(a,b,c,d) =  Σ (3,5,9,11,15)

Complement of this function will be
F'(a,b,c,d) =  Σ (0, 1, 2, 4, 6, 7, 8, 10, 12, 13, 14)

b) F(x,y,z) = Π (2,4,5,7) = Σ (0, 1, 3, 6)
Complement of this function will be:
 F'(x,y,z) = Σ (2,4,5,7)

see man the answer for first one is f=(b+c'+d')(a+b'+c+d')(a'+c'+d')(a'+b+d')

for the second one the answer isf=(x'+y)(x'+z')(x+y'+z)
