Suppose we have a deck of cards, but some of the cards are missing. That is, instead of 52 cards,we have 48 cards. My friend wants to play a magic trick - he wants me to pick a card, remember it,put it back in the deck, then shuffle the deck. He claims he can find that card. Clearly, my friendkeeps track of my card somehow, but if he did not keep track, and the cards were perfectlyrandomized, what would be the probability that he would select my card from the deck? Roundyour answer to 4 decimal places. Recall Canvas truncates trailing Os automatically without loss ofmarks - that means if you enter something like 0.5000, Canvas changes it to 0.5, and you do notlose marks as a result.

Given that, deck of contains 48 cards. Two friends play magic trick in which one select card from…

As shown above, a classic deck of cards is made up of 52 cards, 26 are black, 26 are red. Each color is split into two suits of 13 cards each (clubs and spades are black and hearts and diamonds are red). Each suit is split into 13 individual cards (Ace, 2-10, Jack, Queen, and King). If you select a card at random, what is the probability of getting: a number smaller than 9 (counting the ace as a 1)?
A particular gambling game pays 4 to 1 and has a 20% chance to win. Someone will bet $10, 125 times, and keep track of the total amount won or lost. Which of the following boxes will produce the right answers? Check ALL answers that apply. a. 1 ticket labeled $10 and 4 tickets labeled -$10 b. 20 tickets labeled $10 and 80 tickets labeled -$10 c. 20 tickets labeled 1 and 80 tickets labeled 0 d. 1 ticket labeled $40 and 4 tickets labeled -$10 e. 20 tickets labeled $40 and 80 tickets labeled -$10 f. 1 ticket labeled 1 and 4 tickets labeled 0
(3) Times, Wall Street Journal, and USA Today: In a survey of 150 business travelers, it was found that of three daily newspaper, New York 71 read New York Times; 43 read Wall Street Journal; 34 read USA Today; 30 read New York Times and Wall Street Journal; 25 read New York Times and USA Today; 15 read Wall Street Journal and USA Today; 10 read all three. A person is selected at random from this 150 travelers. (a). What is the probability that the randomly selected person reads New York Times or USA Today but not Wall Street Journal? (b). Given that this traveler read at least one of these three newspapers, what is the probability that he/she read USA Today? (c). Given that this traveler read exactly one of these three newspapers, what is the probability that he/she read Wall Street Journal?
A psychology lab doing research in dreams has 4 rooms (1,2,3, and 4), each containing 2 beds (A and B). Three pairs of twins are being studied tonight. Each pair of twins will be assigned to one of the four rooms, and then each twin will be assigned a specific bed in the room. How many ways are there to organize the experiment? (i.e. How many ways are there to assign the 6 subjects to rooms and beds if each pair of twins must share the same room?) 24 8 192 48 12
A friend of mine is giving a dinner party. His current wine supply includes 7 bottles of zinfandel, 11 of merlot, and 13 of cabernet (he only drinks red wine), all from different wineries. (a) If he wants to serve 3 bottles of zinfandel and serving order is important, how many ways are there to do this? (b) If 6 bottles of wine are to be randomly selected from the 31 for serving, how many ways are there to do this? (c) If 6 bottles are randomly selected, how many ways are there to obtain two bottles of each variety? (d) If 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen? (Round your answer to three decimal places.) (e) If 6 bottles are randomly selected, what is the probability that all of them are the same variety? (Round your answer to three decimal places.)
Suppose that we've decided to test Clara, who works at the Psychic Center, to see if she really has psychic abilities. While talking to her on the phone, we'll thoroughly shuffle a standard deck of 52cards (which is made up of 13 hearts, 13 spades, 13 diamonds, and 13 clubs) and draw one card at random. We'll ask Clara to name the suit (heart, spade, diamond, or club) of the card we drew. After getting her guess, we'll return the card to the deck, thoroughly shuffle the deck, draw another card, and get her guess for the suit of this second card. We'll repeat this process until we've drawn a total of 14 cards and gotten her suit guesses for each.Assume that Clara is not clairvoyant, that is, assume that she randomly guesses on each card. Answer the following. (If necessary, consult a list of formulas.) (a) Estimate the number of cards in the sample for which Clara correctly guesses the suit by giving the mean of the relevant distribution (that is, the expectation of…

a game of chance played historically by Canadian Indians involved throwing eight flat beans into the air and seeing how they fell. The beans were symmetrical and were painted white on one side and black on the other. The bean thrower would win one point if either 0 or 8 white beans came up, and would lose one point for any other configurations. Does the bean thrower have the advantage in this game?
