a letter on the other. He deals you four cards from the deck. Here is what
you see laid out before you on the four cards:
9 J U 2
Your friend then asks you which cards you will need to turn over in order to
determine whether the following rule holds for the deck (assuming these
four cards represent the rest of the deck):
If a vowel is printed on one side of the card, then an even number is
printed on the other side
Which cards do you turn over in order to test this rule? |
