Solution Summary
This problem solution shows you step-by-step how to use a frequency table to find probabilities.
Solution Preview
There are 288 total bridges.
111 + 96 + 30 + 33 + 18 = 288.
a) 3 to 9 ft
There are 111 bridges between 3 and 9 feet. The probability of the height of a randomly chosen arch opening is 3-9 feet is 111/288 = 0.38541 = 38.541%.
b) 30 ft ...
