Question #20220

if a.b is 0 and b.c is 0 then what is a.c?

Expert's answer

Let's build the truth table:

a b c& a.b b.c a.c

1 1 1 1 1 1

1 1 0 1 0 0

1 0 1 0 0 1

1 0 0 0 0 0

0 1 1 0 1 0

0 1 0 0 0 0

0 0 1 0 0 0

0 0 0 0 0 0

As we can see from this table, a.c can take both values (0 or 1) when a.b is 0 and b.c is 0.

a b c& a.b b.c a.c

1 1 1 1 1 1

1 1 0 1 0 0

1 0 1 0 0 1

1 0 0 0 0 0

0 1 1 0 1 0

0 1 0 0 0 0

0 0 1 0 0 0

0 0 0 0 0 0

As we can see from this table, a.c can take both values (0 or 1) when a.b is 0 and b.c is 0.
