How do you determine what are outs in poker and how do they affect your chances of winning a hand?

In Poker, outs are the number of cards left in the deck that can improve your hand. To determine outs, you identify the cards that would give you a winning hand. The more outs you have, the higher your chances of winning the hand. You can calculate your chances of winning by dividing the number of outs by the number of unseen cards.
