1.1.3
If 60% of the population of the US need to have their vision
corrected, we say that the probability that an individual chosen
at random from the population needs vision correction is
P(C)=.60.
a. Estimate the probability that an individual chosen at random
does not need vision correction.
b. If 3 people are chosen at random from the population, what is
the probability that all 3 need correction?
c. If 3 people are chosen at random from the population, what is
the probability that the second person does not need correction
but the first and third do?
d. If 3 people are chosen at random from the population, what is
the probability that 1 out of 3 needs correction?
