It doesn’t disprove the statement. It says if ONE card has an even number then its reverse will be green. If either the green or the 8 has a reverse that makes the statement true, then it does not matter about the blue. The rule says nothing about the blue card.

But if you turn over the blue card and it has an even number, then it disproves the statement, even if the 8 and green cards support the statement.

It is stated in the question that every card has a number on one side and a color on the other.

Actually no – ignore that! It’s neither green nor even, and only one of the cards has to fit the criteria. So, why check the blue? If the 8 isn’t green, then we check the green. If it is not an even number on the reverse then the statement is false.
There are only two ways the statement can be true:
1. The 8 card has a green reverse
2. The green card has an even number on its reverse.
Check the 8 card. If the reverse then the statement is true. If it’s not green, check the green card. If the reverse of the green card contains an even number then the statement is true. If it does not then the statement is false.
We know all we need to know already about the 3 and blue cards. Neither can make the statement true, so we can ignore them.

Surely that has to be turned over following on from the same logic as that for turning over the blue card. We are left to ASSUME that every number is backed by a colour – not necessarily. What if we turn over the 3 card and there’s an even number on its reverse – the statement would be false.

It’s almost like a trick question due to unfamiliar wording not used in normal conversation…or by non-robots lol. The “if p then q” crowd (undergrad philosophy majors) had a major leg up on this one 😂

You may need to turn over the 8 card and the green card – without touching the blue card. The statement says that only ONE of the cards has to have a green side if it’s other side is an even number. Turn over the 8 card – if the other side is green, statement is true, ONE card has an even number with a green reverse. If the 8 card does not have a green reverse then one must turn over the green card. If it contains an even number, then the statement is true and no other cards are relevant. If it does not contain an even number then the statement is false and no other cards are relevant, since the 3 card is odd (thus the reverse is irrelevant) and the blue card is, well, blue – which is neither green nor an even number so it’s reverse is not relevant.

It’s still interesting, to find out in which ways exactly Humans are illogical. Then we can take countermeasures 🙂
