I need 1 page for each question. I need at least 2 citations per question. I need at least 1 references for each question and also list the text as a reference for each page. Course Textbook: Render, B., Stair, R. M., Jr., & Hanna, M. E. (2012). Quantitative analysis for management (11th ed.). Upper Saddle River, NJ: Prentice Hall.I need the references for each question listed after that question, not all together at the end. Please re-write the question and post the response under it.

1. In a production run of 300 units, there are exactly 20 defective items and 280 good items.

(a) What is the probability that a randomly selected item is defective?
(b) If two items are sampled without replacement, what is the probability that both are good?
(c) If two items are randomly sampled without replacement, what is the probability that the first is good but the second is defective?

2. An urn contains 7 blue and 3 yellow chips. If the drawing of chips is done with replacement, determine the probability of:

(a) Drawing three yellow chips.
(b) Drawing a blue chip on the first draw and a yellow chip on the second draw.
