You’d have to firm up your definition of car and vehicle before you could decide that one. Does a hot wheels car count as a car? Does a vehicle have to be large enough to move people or freight?
Comment on Is "If A then B" equal to "B if and only if A"?
Lafari@lemmy.world 8 months agoIf car, then vehicle = true
Car if and only if vehicle = true.
Is this correct?
Therefore “If A then B” = “A if and only if B” (or “If B then A” = “B if and only if A”)?

Don’t confuse this guy with ontological questions.

B can still be true when a is false. iff means that b can only be true when a is true.
