2005 gallup poll found that 7% of teenagers (ages 13 to 17) su er 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.52 (a) calculate the probability that at least one of them su ers from arachnophobia. (b) calculate the probability that exactly 2 of them su er from arachnophobia. (c) calculate the probability that at most 1 of them su ers from arachnophobia. (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?
