Binomial Distribution Use technology (calculator, Microsoft Excel, or Google Sheets) to find the following binomial probabilities. Round to the nearest thousandth. According to the Center for Disease Control, 15% of US adults are estimated to have chronic kidney disease. A random sample of 150 U.S adults are selected. What is the probability that: 1. Exactly 35 have chronic kidney disease? P(r = 35) = 0.002 2. No more than 15 have chronic kidney disease? P(r <$15) = 0.049 3. Thirty...
