Before attempting to solve any problem, make sure that the units are consistent. There are units of feet and inches. To be consistent,let's convert ft to in knowing that there are 12 inches in 1 ft.
9 ft*12 in/1 ft = 108 inches
Now, it also mentions that there are 5 of these. So, the total length would be:
Total Length = 108*5 = 540 inches
Finally, divide the total length to 15 inches.
Number of portions = 540/15 = <em>36 pieces of 15-inch ribbons</em>
We have given the 2 by 2 frequency table.
The probability that a randomly selected book is a nonfiction paperback =
(Number of nonfiction paperback books) / Total number of books
= 23 / 69
= 0.3333
The percentage of nonfiction paperback books is 33.33%
