Let me ask you some questions
Let me present you with four playing cards.
A D 3 6
Rule R is either true or false. Rule R states that a card with a vowel on it always has an even number on
the other side.
Which cards would you have to turn over to prove whether rule R is true or false in this case?
1. A only
2. A and 6
3. D only
4. A and 3 and 6
5. A and 3
6. 3 and 6
7. 3 only
8. A, D, 3 and 6
