There is a letter on one side of each card and a number on the other side. Which card(s) must you turn over to determine whether the following statement is false?

"If a card has a vowel on one side, then it has an even number on the other side."
_____________________________________________________________________

Options (1) and (2)

(1) Has a 80% chance of proving the statement false.

A + even number = cannot determine
A + odd number = statement false

(2) Has a 20% chance of proving the statement false

7 + vowel = statement false
7 + consonant = cannot determine

Unless you are a mindreader you MUST choose "A" first in your effort to prove that the statement in question is false.

So the answer is "A", and that's that.



Careful there Milo, Thanksgiving is coming up. Someone might mistake you for a Thanksgiving Turkey instead of a Christmas one.

You've had it explained to you several times so I won't bother doing it again.

Meanwhile, behind door two is a bag of used dog food. Wanna change your mind about which door you choose?
