AMALIY MASHG’ULOT – 16.
Muammoli masala va topshiriqlar:
1. Agar M to’plamda aniqlangan A(x) va B(x) predikatlar chin qiymatli bo’lsa, u holda ularning chinlik to’plamlari qanday shartlarni qanoatlantirishi kerak:
<sub>1) bunda
I A(x)=0, I B(x)=1;

2) bunda</sub>
I A(x)=0, I B(x)=1,0;
3) ?
A(x)=o, B(x)=1;
3. M={1,2,3,...,20} to’plamda quyidagi predikatlar berilgan:
A(x): «x 5bo’linmaydi» bunda A(x)={1,2,3,4,6,7,8,9,11,12,13,14,16,17,18,19}
B(x): «x juft son» bunda B(x)= {2,4,6,8,10,12,14,16,18,20}
C(x): «x tub son» bunda C(x)={2,3,5,,7,11,13,17,19}
D(x): «x 3 ga karrali» bunda D(x)={3,6,9,12,15,18}
Quyidagi predikatlarning chinlik to’plamini toping:
