An experiment consists of selecting a card from a standard deck of 52 cards, noting whether or not the card is an Face Card (Jack, Queen or King) and returning the card to the deck. This experiment is repeated 10 times. Let X be the random variable representing how many times out of the 10 you observe a Face Card. Suppose that you repeat the experiment 5070 times. Let Y be the random variable representing the number of Face Cards...

Cards are drawn from a standard 52 card deck. After each card is drawn, it is put back in the deck and the cards are reshuffled so that each card drawn is independent of all others. Let N be the random variable that represents the number of cards that are drawn before the second appearance of an Ace. For example, if the sequence of cards drawn was {2, 5, K, 7, A, 5, 3, J, A, ...} then N would...

1.Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace the card, and draw another card. You repeat this process until you have drawn 18 cards in all. What is the probability of drawing at least 5 diamonds? 2.For the experiment above, let ? X denote the number of diamonds that are drawn. For this random variable, find its expected value and standard deviation. ?(?)= σ =

Suppose that we draw two cards from a standard deck of 52 playing cards, where ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen and king each appear four times (once in each suit). Suppose that it is equally likely that we draw any card remaining in the deck. Let X be the value of the first card, where we count aces as 1, jacks as 11, queens as 12, and kings as 13. Let Y be...
