3) A bottle of water is supposed to have 20 ounces. The bottling company has determined that 98% of bottles have the correct amount. Which of the following describes a binomial experiment that would determine the probability that a case of 24 bottles has all bottles properly filled?

n=24, p=0.98, x=24

n=24, p=0.98, x=20

n=0, p=0.98, x=36

n=24, p=0.98, x=1
