ABCD to be sure that it is correct for all cards

You have to turn over 2 cards. Card A and Card C because card A has a vowel on it and Card C has an even number on it.

In order the hypothesis you would need to turn over all for cards. This is because you want to see all of your possible outcomes. This is because when you are testing a theory you want to try and prove it wrong or prove it right

I think you just have to flip card C because the hypothesis is only asking for a card that has an even number. The card that defiantly has an even number is card C. The hypothesis will be correct is card C has a vowel on the other side.

In order to test the hypothesis you must turn over all four cards because in order to prove the vowels and even numbers are on the same card and the consonants go with the odd numbers.

Turn over both cards A and C.

You must turn over two cards, which are cards A and C because our hypothesis is only testing for vowels and even numbers.

I believe just flipping C will be enough to test the hypothesis. This is because we’re only concerned about vowel/even number cards.

All four – ABCD, if you flip over A and C and they happen to have a vowel and even number, that doesn’t mean the other cards can’t have a mismatch odd number and vowel or even number and consonant

Turn over card A and C, because card A is a vowel and card C is an even number

I would say turn over the one vowel because that is what ur hypothesis states.

A and C. By turning over both A and C you can see if both vowels have even numbers, seeing as the hypothesis is testing vowels against even numbers.

We only need to turn over card A and Card D to test the hypothesis. This is because a Vowel will have an even number on its opposite side if-and-only-if the hypothesis is true. If we turn over the 3, this will either verify or invalidate our hypothesis. This is also the case if we Turn over the E card.
