Just card A
I most turn over card A and card C. E is a vowel and 2 is a even number so card A is E and Card C is 2.
A B C D
Two cards, A and C, because they each are a card with a present vowel or even number, which will easily prove if the hypothesis is true or not.
Card A and C to test one of the number cards and one of the cards with a letter on it
Turn over card A and C. A has a vowel on one side so we have to check if it has an even number on the there side. C has an even number so we have to turn it over to see if it has a vowel on the other side. B and D are irrelevant because they do not have the vowel/even number to start.
Must turn over card c because thats the only card with an even number. And in oder to test your hypothesis that card needs to be flipped
A and C would fully conclude for those cards that an even number has a vowel or a vowel has a even number. If either card does not fit the hypothesis then the hypothesis is false.
All four cards (A B C D) because the hypothesis is not true so we do not know if an odd numbered card has a vowel or not.
I think you have to turn over Card A and Card C because the hypothesis only states something about even numbers and vowels, not odd numbers and consonants. So since we’re only proving that if you turn over a vowel, you get an even number, to test that, you would have to turn over Card A, which has a vowel, and Card C which has an even number to see if the hypothesis is correct.
Card A only because the hypothesis says that every card with a vowel on one side has an even number on its opposite side. Also, it says test the hypothesis not prove that hypothesis.
Card A and card C
Card A & C would need to be flipped to test the hypothesis.
Card A B C D would need to be flipped to test the hypothesis.
