Question

Can someone explain "if and only if"? If P and Q are both False, why is "P iff Q" True?

Answer 1

I apologize my question ended up in CS rather than Math. OpenStudy is extremely buggy for me and I am not sure why.

Answer 2

its a bi conditional statement. An example
P: I am a dog
Q: i have a tale
i am NOT a dog if and only if i do NOT have a tale
this is true.

Answer 3

notice in the statement p and q are both false
