The probability that a person in the United States has dark brown eye color is 18%.
Three unrelated people in the United States are selected at random.
a)
What is the probability that all three have
dark brown eye colour
?
b)
What is the probability that at least
one person has dark brown eye colour? (Hint: use
a complement rule)
B says complement rule but to simply do 1.0-0.82=0.18 seems too simple to be correct and doesn't account for the fact that there is 3 people so I'm not sure if it should be that or 0.18x0.82x0.82???
