Q6.3 If a biscuit is picked randomly from the factory's stock and is found not to contain nuts, then it must be a NoNut biscuit.
Q6.4 If two biscuits of two different brands are picked randomly from the factory and both contain seeds, then one of them has to be a NoNut biscuit.
Q6.5 If a biscuit does not contain nuts, it must contain seeds.
Q6.3 Given that NoNut is the only brand not to contain nuts, any biscuit with no nuts has to be a NoNut biscuit.

Q6.5 Nothing points to the fact that NoNut biscuits contain seeds.
