How many ping pong balls fit in a Boeing plane? If you had three baskets, one containing apples, the other one oranges and the third one apples and oranges, how would you find which basket had which by asking only one question given that all baskets were mislabeled? (i.e if the basket had the label oranges, it could have either apples or oranges and apples, but not just oranges). If a Russian gangster kidnapped you, put two bullets in his/her gun back to back and shot at you once (no bullet was fired) would you rather having him/her fire again or spin the canister first, then fire?
