Juste une réponse rapide ici, la guerre en fait es un jeu, car la façon dont les joueurs choisissent les cartes affecte le résultat. Vous pouvez choisir de ramasser les cartes dans un ordre différent après chaque tour. Mais il est très difficile de jouer de manière stratégique.
Pour ce qui est de la question à l'étude, j'ai construit ma propre simulation, et pour 5 essais, avec brassage, j'ai obtenu :
58, 144, 354, 428, 189
Cela représente une moyenne de 234 tirs. Évidemment, vous pouvez faire plus d'essais, pour obtenir un chiffre plus précis, mais c'est définitivement une longue partie à jouer !
