Jenae noticed that many of her co-workers would opt for the coffee that appeared to be most recently brewed, regardless of the flavor of the coffee offered. This leads her to believe that what she was witnessing was not really representative of everyone's true flavor preferences. She adapted her experimental study accordingly.Select one control in Jenae's experimental study.Jenae monitors the habits of the co-workers who do not drink coffee.Jenae keeps the same amount of sugar and artificial sweetener at each location.Jenae places condiments at random places throughout the kitchen.Jenae takes note of the frequency in which co-workers refill their coffee mugs.

iva loves coffee but her nurse friend recommended reducing her coffee intake and she decided to do it by using a fair 10-sided die to determine her coffee intake according to the following simple model. If she drank coffee yesterday then she will drink any other hot drink (no-coffee) today if she rolls a seven or less, otherwise she will drink coffee. If she drank no-coffee yesterday then she will drink no-coffee today if she rolls a six or more, otherwise she will drink coffee. Let Cn be the event that she drinks coffee on the nth day and Nn be the event that she drinks no-coffee on the nth day. (a) Using the information given, write down the value of these probabilities P (Cn | Cn−1), P (Cn | Nn−1), P (Nn | Cn−1) and P (Nn | Nn−1). [2 marks] (b) Suppose Siva drinks no-coffee on day 1, that is, P(N1) = 1. i. What is the probability that Siva drinks no-coffee on day 2? [1 mark] ii. What is the probability that Siva drinks coffee on day 2? [1 mark] iii. Find P(C3 ∩ C2) and P(C3 ∩ N2). [2 marks] iv. What is the probability that Siva drinks coffee on day 3? [1 mark] v. Suppose Siva drinks coffee on day 3. What is the probability that she drank no-coffee on day 2?
