Please forgive the total ignorance of the question...being a fairly seasoned player, BUT, assume 10 payers, nlhe, and it goes heads up with one on the flush draw after the turn (four flush). How is it we use 52-4(flop+turn)-2(hole cards)=46 cards with 9(left of suit)/46 as the outs for the flush on the river, when 16 other cards, (eight players x two hole cards) have folded. Even with random distribution of suits, why do we not discount for these cards?
