On a recent Saturday, a total of 1,112 people visited a local library. Of these people: 266 were under age 10, 496 were aged 10–18, 189 were aged 19–30, and the rest were more than 30 years old.One person is sampled at random. What is the probability that the person is less than 19 years old?
A concern for many adults is that computers and the Internet are reducing privacy. A survey conducted by Peter D. Hart Research Associates for the Shell Poll was reported in the USA Today. According to the survey, 37% of adults are concerned that employers are monitoring phone calls. Use the binomial distribution formula to calculate the probability that out of five adults, exactly three are concerned that employers are monitoring their phone calls. Select one: O a. 1.85 Ob. 0.799 Oc. 0.201 d. 3.15
According to a study done by Nick Wilson of Otago University Wellington, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. Suppose you sit on a bench in a mall and observe people's habits as they sneeze. Complete parts (a) through (c). (a) What is the probability that among 16 randomly observed individuals, exactly 4 do not cover their mouth when sneezing? Using the binomial distribution, the probability is (Round to four decimal places as needed.) (b) What is the probability that among 16 randomly observed individuals, fewer than 5 do not cover their mouth when sneezing? Using the binomial distribution, the probability is (Round to four decimal places as needed.) (c) Would you be surprised if, after observing 16 individuals, fewer than half covered their mouth when sneezing? Why? it be surprising, because using the binomial distribution, the probability is (Round to four decimal places as needed.) which is 0.05.
