Question Once again you are given four cards. Each card has a number printed on one side and a letter on the other side. Which are the only two cards you need to turn over to check whether the following rule holds?
"If a card has a consonant on one side, then it has an odd number on the other side."
We need to turn over B and 8, in order to check whether the rule holds.
Rule is broken, if any of the one condition occurs :
If B has an even number on the other side.
If 8 has a consonant on the other side.
