The probability of busting in Blackjack depends on the value of your current hand and the remaining cards in the deck. It’s determined by calculating the likelihood that drawing another card will push your total over 21. For example, if you have a hand total of 12, drawing a 10, Jack, Queen, King, or Ace would cause a bust. The probability increases if there are more high cards left in the deck. The calculation is influenced by the number of decks used, with multi-deck games being slightly harder to predict due to the larger number of cards in play. Overall, bust probability depends on both the current hand and deck composition.
