You are a customer support manager at Apple. Your staff are rated by the customer after each support call they close. Each month you randomally sample the cases of each employee and if you find sufficient "Perfect" cases then you give the employee a $250 award. This month you give the award if you find (at least) 4 Perfect cases. Suppose an employee handled 42 cases of which 7 are Perfect cases and 35 are not. Assume you sample 10 of the cases of that employee. Answer the following: a. What is the probability that you will find no Perfect cases? nothing. (Round to four decimal places as needed.) b. What is the probability that there will be at least 1 Perfcet case? (Round to four decimal places as needed.) c. What is the probability that there will be 4 Perfect cases? (Round to four decimal places as needed.) d. What is the probability that the award will not be given? (Round to four decimal places as needed.)
Suppose you roll 4 fair standard 8-sided dice, noting the number showing on each die. Let X be the random variable denoting the number of 3's showing. Write all possible numerical values for X. Enter a list of numbers in ascending order, separated by commas.
1. Let ? = {5, 10, 15, ⋯ ⋯ ⋯ ⋯ ,90, 95, 100}.When a number is randomly chosen from the set S,let the random variable X represent the value of the chosen number.(a) Find ?(? ≤ 90).(b) Find ?(? ≤ 20 | ? is odd).
A student forgot to prepare for a quiz. There are three True/False questions in that quiz. The student decide to flip a coin and randomly give an answer to each question. Head for True and tail for False. This is a fair coin, so the probability to flip a head is 0.5. Suppose we use X to denote the number of True/False questions this student answered correctly. 1. What type of variable is X? a) A discrete random variable b) A continuous random variable c) A normal random variable 2, . What's the probability that the student got all three questions correct? a) (0.5)(0.5)(0.5) b) 3(0.5)(0.5)(0.5) c) 0.5 3. What's the probability that the student only got one of the three questions correct? a) 3(0.5)(0.5)(0.5) b) (0.5)(0.5)(0.5) c) (0.5)(0.5) d) 0.5 4. What's the expected value of X? a) 3(0.5) b) 2 c) 1 d) 3 5. If the True or False questions worth 2 points each, what's the expected points earned by this student from those three True or False questions? a) 3 b) 6 c) 2 d) 0.5

An ice cream parlor serves 10 flavors of ice cream. Carrie and Jimmy each randomly and independently choose 3 out of those 10 flavors. Use the method of indicators to find the expected number of flavors chosen by both Carrie and Jimmy and simplify your final answer**** ****Each person has to choose 3 different flavors (Vanilla- Vanilla-Chocolate is not ok) but their flavors are allowed to overlap (Chocolate-Vanilla-Strawberry for Carrie and Chocolate- Blueberry-Mint for Jimmy is ok). The order of flavors doesn’t matter.
In screening for a certain disease, the probability that a healthy person wrongly gets a positive result is0.05. The probability that a diseased person wrongly gets a negative result is 0.002. The overall rate ofthe disease in the population being screened is 1%. If my test gives a positive result, what is theprobability I actually have the disease? ( dont hand writing solution)
Suppose you are taking a multiple-choice test with c choices for each ques- tion. In answering a question on this test, the probability that you know the answer is you don't know the answer, you choose one at random. What is the probability that you knew the answer to a question, given that you answered it correctly? 2. р. If

18 that of a 37 In a popular casino game, you can bet one whether a ball will fall in an arc on a wheel colored red, black, or green. Say the probability of a red outcome is 18 and that of a green outcome is 37' Suppose someone makes a $10 bet on black. Find the expected net winnings for this single bet. Interpret the 37 black outcome is result. Choose the correct answer below and fill in the answer box to complete your choice. (Round to three decimal places as needed.) dollars per bet. O A. If the $10 bet on black was placed a very large number of times, the average winnings would be O B. On average, a person is expected to win dollars for any bet on the roulette wheel. dollars. O C. If the $10 bet on black was placed a very large number of times, the bettor would win a total of O D. A person will win dollars every time a $10 bet was placed on black.
