3.32 Arachnophobia: A 2005 Gallup Poll found that 7% of teenagers (ages 13 to 17) suffer from arachnophobia and are extremely afraid of spiders. At a summer camp there are 10 teenagers sleeping in each tent. Assume that these 10 teenagers are independent of each other. (a) Calculate the probability that at least one of them suffers from arachnophobia. (please round to four decimal places) (b) Calculate the probability that exactly 2 of them suffer from arachnophobia? (please round to four decimal places) (c) Calculate the probability that at most 1 of them suffers from arachnophobia? (please round to four decimal places) (d) If the camp counselor wants to make sure no more than 1 teenager in each tent is afraid of spiders, does it seem reasonable for him to randomly assign teenagers to tents?

Based on a poll, 70% of Internet users are more careful about personal information when using a public Wi-Fi hotspot. What is the probability that among threethree randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot? How is the result affected by the additional information that the survey subjects volunteered to respond? The probability that at least one of them is careful about personal information is? (Round to three decimal places as needed.) How is the result affected by the additional information that the survey subjects volunteered to respond? A. It is very possible that the result is not valid because not everyone uses public Wi-Fi. B. The result should not be impacted by this because volunteers are likely to have the most relevant responses. C. The result should not be impacted by this because there is no reason to lie when responding. D. It is very possible that…
