Card Hypothesis

How much evidence is enough evidence?

FACT: Each card has a number on one side and a letter on the other.

HYPOTHESIS: Every card that has a vowel on one side has an even number on its opposite side.

THE TEST: Which card or cards must you turn over in order to test the Hypothesis?

(Obviously, you COULD turn over all four cards, and perhaps you must. But if you can do it with fewer, you’ll save yourself time and energy gathering your evidence.)

    You can flip over all the cards. However, I would say G and 3.
