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. Round your answer to 4 decimal places. b) Calculate the probability that exactly 2 of them suffer from arachnophobia? Round your answer to 4 decimal places. c) Calculate the probability that at most 1 of them suffers from arachnophobia? Round your answer to 4 decimal places.
A manufacturer of liquid crystal displays (LCDs) is studying their production lines. The probability of sampling a defective LCD is 0.1. A sample of 5 LCDs is taken. You may assume that an LCD being defective is independent of any of the others being defective.

The probability of a randomly selected adult in one country being infected with a certain virus is 0.005. In tests for the virus, blood samples from 14 people are combined. What is the probability that the combined sample tests positive for the virus? Is it unlikely for such a combined sample to test positive? Note that the combined sample tests positive if at least one person has the virus. The probability that the combined sample will test positive is (Round to three decimal places as needed.) Is it unlikely for such a combined sample to test positive? O A. It is unlikely for such a combined sample to test positive, because the probability that the combined sample will test positive is less than or equal to 0.05. O B. It is not unlikely for such a combined sample to test positive, because the probability that the combined sample will test positive is less than or equal to 0.05. OC. It is not unlikely for such a combined sample to test positive, because the probability that the…
