. Suppose 51% of the individuals in a certain population have brown eyes, 32% have blue eyes, and
the remainder have green eyes. Consider a random sample of 10 people from this population.
(a) What is the probability that 5 of the 10 people have brown eyes, 3 of 10 have blue eyes, and
the other 2 have green eyes?
(b) What is the probability that exactly one person in the sample has blue eyes and exactly one
has green eyes?
(c) What is the probability that at least 7 of the 10 people have brown eyes? [Hint: Think of
brown as a success and all other eye colors as failures.]
