(a) Using the binomial distribution, what is the probability that among 10 randomly observed individuals, exactly 5 do not cover their mouth when sneezing? The probability is . (Round to four decimal places as needed.) (b) Using the binomial distribution, what is the probability that among 10 randomly observed individuals, fewer than 6 do not cover their mouth when sneezing? The probability is O. (Round to four decimal places as needed.) (c) Using the binomial distribution, would you be surprised if, after observing 10 individuals, fewer than half covered their mouth when sneezing? Why? it (Round to four decimal places as needed.) be surprising, because the probability is, which is 0.05.
