In a region, there is a 0.9 probability chance that a randomly selected person of the population has brown eyes. Assume 15 people are randomly selected. Complete parts (a) through (d) below. a. Find the probability that all of the selected people have brown eyes.
The probability that all of the 15 selected people have brown eyes is 0.205. (Round to three decimal places as needed.)
b. Find the probability that exactly 14 of the selected people have brown eyes.
The probability that exactly 14 of the selected people have brown eyes is 0.343. (Round to three decimal places as needed.)
c. Find the probability that the number of selected people that have brown eyes is 13 or more. The probability that the number of selected people that have brown eyes is 13 or more. (Round to three decimal places as needed.)
