* Question Completion Status: QUESTION 18 Suppose that two people each roll the die independently of each other. What is the probability that both people roll a 3? a. 0.20 O b. 0.40 O c. 0.10 O d. 0.04 QUESTION 19 Suppose that we continue to flip a fair, balanced coin until a head occurs for the first time, at which point we stop and record the random variable X = the total number of flips that it took to obtain the first head. Which one of the following describes this experiment? [Formula Sheet] a. This is not a Binomial experiment because the outcomes of the trials are not independent. b. This is not a Binomial experiment because there is not a known number of trials. c. This is a Binomial experiment. d. This is not a Binomial experiment because the P(success) is not the same for every trial. QUESTION 20 Use the following information for the next two problems. At a particular pizzeria, approximately 40% of all orders are carry-out. [ Formula Sheet] Suppose that 10 orders are selected independently of one another. Find the probability that less than 3 of them are carry-out orders. a. 0.167 b. 0.064 O c. 0.215 Od. 0.382 QUESTION 21 Which one of the following gives the mean and the standard deviation of the number of orders (out of 10) that would be carry-out orders? a. Mean = 10 Standard deviation = 0.40 Click Save and Submit to save and submit. Click Save All Answers to save all answers
