Bridget is a bridge player. She has devised a point system for scoring the hand she has been dealt. She assigns four points for every ace in her hand, three points for every king in her hand, two points for every queen in her hand, and one point for every jack in her hand. If she is dealt a 13-card hand without replacement, from a well-shuffled deck find the expected number of points in her hand.

2. (10 points) Suppose you are playing blackjack against a dealer. In a freshly shuffled deck, what is the probability that either you or the dealer is dealt a blackjack? (Recall the game of blackjack is played with each player obtaining two cards at random from a regular deck. We say these two cards form a blackjack if one card is an ace and the other card is either a 10, Jack, Queen or King)

how many diamonds are in a deck of cards?
A deck of cards contains 52 cards. They are divided into four suits: spades, diamonds, clubs and hearts. Each suit has 13 cards: ace through 10, and three picture cards: Jack, Queen, and King. Two suits are red in color: hearts and diamonds. Two suits are black in color: clubs and spades.Use this information to compute the probabilities asked for below and leave them in fraction form. All events are in the context that three cards are dealt from a...

4. In one version of the game played by a dealer and a player, 2 cards of a standard 52-card bridge deck are dealt to the player and 2 cards to the dealer. For this exercise, assume that drawing an ace and a face card (Jack, Queen and King for each shape) is called blackjack. If the dealer does not draw a blackjack and the player does, the player wins. If both the dealer and player draw blackjack, a tie...

Prisha has a standard deck of 52 playing cards. The deck contains 4 suits (hearts, diamonds, clubs, and spades), and each suit contains 13 cards labeled 2 through 10, as well as jack, queen, king, and ace. Four friends are trying to determine some probabilities related to drawing cards from the deck. Two cards will be randomly drawn from the deck, and after the first card is drawn, it is not replaced before the second card is drawn. Consider the...

The statement: Dim aryintCards(4,14) as Integer (See AryCardExample.xlsx excel spreadsheet) declares an array which the first subscript 1-4 are the four suits and the second subscript ranges over the card denominations: 1-14: Ace, 2, ..., 10, Jack, Queen, King, Ace (repeated). First subscript of 0 is Total of each denomination. Second subscript of 0 is Total of...
