According to a study done by a university student, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267. suppose you sit on a bench in a mall and observe people's habits as they sneeze.

(a) what is the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when sneezing?

(b) what is the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when sneezing? (

c) would you be surprised if, after observing 12 individuals, fewer than half covered their mouth when sneezing? why?

a) 0.0037, b) 0.8053, c) 0.0206.

Step-by-step explanation:

Since we have given that

n = 12 and p = 0.267

So, q = 1-0.267 = 0.733

(​a) What is the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when​ sneezing?

(​b) What is the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when​ sneezing?​(

​c) Would you be surprised​ if, after observing 12 individuals, fewer than half covered their mouth when​ sneezing? Why?

Hence, a) 0.0037, b) 0.8053, c) 0.0206.
