- 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 .05.

a - NO, because the probability of this occurring is not small
b- YES, because the probability of this occurring is very small
c- NO, because the probability of this occurring is very small
d- YES, because the probability of this occurring is not small
