brianna is taking part in a lottery for a room in one of the new dorms at her college. she is guaranteed a space, but se will have to draw a card randomly to determine exactly which room she will have. Each card has the name of one dorm ,x,y, OR Z AND ALSO HAS A TWO-PERSON ROOM NUMBER OR AN APARTMENT NUMBER.THIRTY PERCENT OF THE AVAILABILITY SPACES ARE IN X, 50% IN Y, AND 20% IN Z. HALF OF THE AVAILABLE SPACES ARE IN X ARE IN ROOM, 40% OF Y'S SPACES ARE IN ROOMS AND 30% OF THE SPACES IN Z ARE IN ROOMS. WHAT IS THE PROBABILITY THAT BRIANNA WILL BE ASSIGNED AS APARTMENT IN ONE OF THE THREE DORMS?

Abdul has one die in his left hand and one in his righthand. One die has six dots painted on each face, and theother has one dot painted on two of the faces and six dotspainted on each of the other four faces. Greta is to pick onedie (either “left” or “right”) and will receive $10 for eachdot painted on the die that is picked. Before choosing, Gretamay pay Abdul $15, and he will toss the die in his left handand tell her how many dots are painted on the face thatcomes up. Use a decision tree to determine how to maximizeGreta’s profit. Also determine EVSI and EVPI.
Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1). Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.) Xi 2 –1 P(xi) What is Miguel’s expected value from playing the game? Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays? What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation. A game at the…

The first 25 random numbers, ignoring repeats, represent the subjects assigned to the new model group. The remaining 25 subjects will wear the original model. months, the wear on the shoes will be determined using the depth of the tread and flexibility of the toe box. The wear between the new model and the original model will then be compared. The subjects' names are written on equal-sized slips of paper and placed into a hat. A researcher then reaches in and pulls out 25 slips of paper. These subjects are assigned to the new model group. The remaining 25 subjects will be…

The college hiking club is having a fund raiser to buy new equipment for fall and winter outings. The club is selling Chinese fortune cookies at a price of $1 per cookie. Each cookie contains a piece of paper with a different number written on it. A random drawing will determine which number is the winner of a dinner for two at a local Chinese restaurant. The dinner is valued at $35. Since fortune cookies are donated to the club, we can ignore the cost of the cookies. The club sold 725 cookies before the drawing. Lisa bought 18 cookies. What is the probability she will not win the dinner for two? Write your answer as a fraction in simplest form, if one exists.
