Work Step by Step
p: The lines go down.
q: The transformer blows.
r: We have power.
We have power if and only if it’s not true that both the lines go down and the transformer blows.
The symbolic representation is:
~(p ᴧ q): It’s not true that both the lines go down and the transformer blows.
r ↔ ~(p ᴧ q) : We have power if and only if it’s not true that both the lines go down and the transformer blows.
