Probabilities are used to determine the chances of events
The probability that two are nearsighted and one is not, is 0.0645
<h3>How to determine the probability</h3>
The given parameters are:
n = 3 -- the number of Australians selected
r = 2 --- the number that are nearsighted
p = 16% --- the proportion that are nearsighted.
The probability that two are nearsighted and one is not, is calculated using the following binomial probability formula
So, we have:
Hence, the probability that two are nearsighted and one is not, is 0.0645
