Alright sci prove you are smart. Your friend Aristo brought cards. On each card there is a letter on one side and a number on the other side. He lays the 4 cards shown in the picture infront of you and says: If theres a vowel on one side there is an even number on the other side. How many cards do you need to flip in order to know if he is telling the truth?

Perhaps i should ask which ones and why

2
"E" and "7"
"E" must be checked for an even number
"V" could have any number under these rules
"2" could have any letter under these rules
"7" must be checked for a non-vowel
All this assumes "On each card there is a letter on one side and a number on the other side" is know for certain, and isn't part of "is he telling the truth?"

E
E to check an even number is on the other side
V, 2 and 7 are unimportant, since Aristo didn't say, vowels and even numbers are mutually exclusive.
In other words, he didn't state that a consonant can't have an even number on the other side. Only that a vowel will have an even number on the other side

I stand corrected
E and 7

You're overlooking the fact that under Aristo's rules, "7" must not have a vowel on the other side.

I could not help but notice your png was not optimized anon.
I have optimized your png.
Your png is now optimized.
Um, just the vowel as he said, flip the E. So the answer is 1. Read what he said carefully. You don't have to be smart, just literate with that question.
Joke's on you, I don't have friends.

nope, you have to check the 7 as well, because if there's a vowel on the other side, then the rule is wrong
So the main question here is: Are the backside and frontside differenciated or is it irrelevant? If theres no difference the 7 has to be checked as well since the rule would be false if there is a vowel. If they just have 1 frontside then you only have to flip the E. THis was a question in a test i took yesterday.
