Three squares are chosen at random from a standard 8 × 8 chessboard. What is the probability that no pair of squares shares an edge?
2. Given a standard shuffled deck of 52 cards, you flip through the deck starting at the top until you reach the first Ace (A). What position does that A need to be in to give an equal probability of running into another A or a 2 after that? (we have not specified whether you have already seen a 2, or not, prior to flipping the first A).
can someone pleaseee help, I don't know how to start
