We were discussing about a logic question with my friends. And we haven't agreed the right answer.
I want to ask this question to you. If you answer we will be happy.
Sorry for bad English.
These are the rules:
- You will be given a hyphothesis to be examined on.
- You will be shown some cards. One side of the card is a letter and other side of the card is number.
- You are going to see only one side of the card.
- And you are going to decide if you switch(to look or check) or not the other side of the card to examine the hyphothesis.
Hyphothesis: If one side of a card is letter 'D', other side of the card has to be number '7'.
You see these cards: 7, A, 8, 9, D, G
Which cards are you going to switch to examine the hyphothesis?
