4 A city had a parade for a winning basketball team. Since it was put together in five days, only 25% of the groups asked to be in the parade were able to participate. If the parade committee asked 124 groups to participate, how many were able to be in the parade? A.11 B.31 C.99 D.26
In roulette, the numbers from 1 to 36 are evenly distributed between red and black. A player who bets $1 on black wins $1 (and gets the $1 bet back) if the ball comes to rest on black; otherwise (if the ball lands on red, 0, or 00), the $1 bet is lost. One option in a roulette game is to bet $19 on red. If the ball lands on red, you get to keep the $19 you paid to play the game, and you are awarded $21. If the ball lands elsewhere, you are awarded nothing, and the $19 that you bet is collected. What is the expected value of the game? The expected value for playing roulette if you bet $19 on red is approximately $ (Round to the nearest cent as needed.)

g) The Lady Tasting Tea Experiment. An English lady, Muriel Bristol, claimed that she can tell whether tea or milk was added first to a cup. So as a researcher, you want to test whether she can really tell whether tea or milk was added first. But how would you do it? A possible research design: Give her eight cups, four where tea is added first and the other four where milk is added first, in random order. Then ask her to pick out the four cups where the milk is added first. After you conducted the experiment and collected the data, how do you decide whether she can truly tell the difference or she was just guessing. Our intuition tells us that the more cups she gets correctly, the more likely that she is NOT guessing. "If the Lady is just guessing, the probability of getting it all correctly is 1.4%." Now using your knowledge on combinatorics and probability, explain how this number was calculated? h) Suppose you flip four fair coins. What is the probability that you will get all…
Dr. A. Ventura is interested in determining what kinds and how many pets people own in Bakersfield. He stands outside Petco and asks people what kind of pet they own. This is the result of his survey: dog=1; cat=2; bird=3; reptile=4; fish=5; other=6 1,1,2,2,2,1,1,3,2,3,1,1,1,2,2,4,4,2,2,1,1,1,5,4,3,4,1,1,1,2,2,6,1,1,2,2,1,2,1,2,6,3,4,5
Ten thousand raffle tickets are sold for $2 each. One first prize of $1400, 3 second prizes of $800 each, and 9 third prizes of $400 each are to be awarded, with all winners selected randomly. If you purchase one ticket, what are your expected winnings? Round your answer to the nearest cent.
Local parents and their children were invited to the grand opening of a daycare center. Each of the 153 attendees got to spin a wheel to win a prize. The table below summarizes the data on the attendees and their prizes. Pencil Cup Magnet Parent 17 48 7 Child 16 36 29 Suppose an attendee from the grand opening is chosen at random. Answer each part. Do not round intermediate computations, and round your answers to the nearest hundredth. (If necessary, consult a list of formulas.) (a) What is the probability that the attendee is a child or won a pencil? ? (b) What is the probability that the attendee is a parent, given that the attendee won a cup?
A teacher announces a pop quiz for which the student is completely unprepared. The quiz consists of 20 true-false questions. The student has no choice but to guess the answer randomly for all 20 questions. The accompanying table gives the 20 correct answers, which were actually randomly generated. Complete parts a. and b. below. a. How many questions can the student expect to answer correctly simply by guessing? b. What percentage of answers were true, and what percentage would you expect? Why are they not necessarily identical? The percentage of answers that were true was? The expected percentage of answers that would be true is? Why are these answers not necessarily identical? A. With random phenomena, the proportion of times that something happens is highly predictable in the short run. B. With random phenomena, the proportion of times that something happens is highly random and variable in the short run. C. With random phenomena, the…

A new game is being introduced at the Hard Rock Cafe. A ball is spun around a wheel until it comes to rest in one of many spots. Whatever is listed in that spot will be the player's winnings. If the wheel has 7 spots labeled $1, 9 spots labeled $2, and 6 spots labeled $10, how much should a player expect to win on average? Round to the nearest cent.
