Using it's concept, it is found that there is a 85% probability that the moviegoer is not in the 65-74 age range.
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, the total number of moviegoers is given by:
T = 1224 + 1220 + 940 + 830 + 730 = 4944.
Out of those, the number not in the 65-74 age range is:
D = 4944 - 730 = 4214.
Hence, the probability is given by:
p = 4214/4944 = 0.85 = 85%.
There is a 85% probability that the moviegoer is not in the 65-74 age range.
