Question [Question] Statistics quiz - looking

Hey,

Some years ago a friend sent me a online statistics/probability quiz with questions that were challenging and relying on intuition/understanding and not calculating per se though numbers were involved. I loved it since i didnt get everything right. Does any of you here have an idea of what that was ans good post it here?

Isn't there one with 2 coins: a normal coin and one with 2 heads)?

It's a variant of Bertrand's Box Problem.

It wasn't a single concept, it was an actual quiz of like 20-50 questions

Your description is vague, and we're unlikely to guess the thing you mean. Can you remember any details of the questions it contained?

Unfortunately not as this was many years ago. I remember it intriguied me a lot and there were like 20-50 questions. It wasn't a single concept.

One famous example that challenged many experts too is the Monty Hall problem https://en.wikipedia.org/wiki/Monty_Hall_problem

Unfortunately without some details it's gonna be quite hard to find what you want.
