My son is autistic and he likes playing war a lot. We usually play a couple games everyday during breakfast before school. Deck was lazily shuffled after each game, like two or three times, but I guess let’s just assume it’s random. So deck was divided 26 cards each and we started the game. Once you get two cards that match, it’s a war. You lay 3 cards face down and then flip the 4th card to determine the winner. If the 4th card matches, you lay 3 face down again and flip the next card to see who wins. So we had 5 matches in a row, on the last one we only had enough cards to lay one face down, and then flipped the final card and it matched again. What are the odds of this?
