In a region, 90% of the population have brown eyes. if 15 people are randomly selected, find the probability that at least 13 of them have brown eyes. is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes? why or why not? the probability that at least 13 of the 15 people selected have brown eyes is nothing. (round to three decimal places as needed.) is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes? note that a small probability is one that is less than 0.05. a. no, because the probability of this occurring is very small. b. yes, because the probability of this occurring is not small. c. yes, because the probability of this occurring is very small. d. no, because the probability of this occurring is not small.
