Пишу так. v - это OR, ^ - AND, ¬ - ! чтобы удобнее было
1) !x OR !y OR z
F(1, 0, 0) = 0 OR 1 OR 0 = 1 неверно.
2) X AND Y AND Z
F(1, 0, 0) = 1 AND 0 AND 0 = 0 верно.
F(0, 0, 0) = 0 AND 0 AND 0 = 0 неверно.
3) !x AND !y AND !z
F(1, 0, 0) = 0 AND 1 AND 1 = 0 верно.
F(0, 0, 0) = 1 AND 1 AND 1= 1 верно
F(1, 1, 1) = 0 AND 0 AND 0 = 0 верно
ответ 3.
