The contrapositive of the statement p ⇒ q is not q ⇒ not p and both the statements are equivalent.
So, the contrapositive of the statement "If it is Friday, then Bruce has beans for supper" is "If Bruce does not have beans for supper, then, it is not Friday"
This is the last statement given and is the answer.
