You are practicing playing blackjack. in blackjack you try to draw cards from a standard deck to get as close to the sum of 21 as possible without going over. since you are by yourself, you are just drawing cards to see how close you can get to 21. suppose that the first card you draw is an ace of hearts. if you do not place that card back in the deck, what is the probability that your next card will also be an ace (of any suit? )
