term paper-Goo 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. >0.5160 (please round to four decimal places) (b) Calculate the probability that exactly 2 of them suffer from arachnophobia? = 0.1233 (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) 08482 (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? Yes, a 15% chance of at least two being afraid of spiders in the same tent is not that high of a probability Yes, an 85% chance of at least two being afraid of spiders in the same tent is not that high of a probability O No, there is more than a 15% chance that at
least two teenagers in the same tent will be afraid of spiders O No, there is almost an 85% chance that at least two teenagers in the same tent will be afraid of spiders Dayeh, T.docx Geranpayeh, C...docx ^ a Geranpayeh, T. dock A Geranpayeh, T.docx 420 B0/-
