To Prove Study=Fail

To prove: Study = Fail

We know,

If we study we won't fail but if we don't study we'll fail

I.e.     study = not fail........... (I)

          Not study = fail.......... (ii)

Now, adding equation (I) and (ii),

Study + not study = not fail + fail

Study (1 + not) = Fail (1 + not)

:.  Study = Fail............Proved

:.  Study = Fail............Proved
