Given:
24,000 books
Between 3 and 4 books will have a printing error in every 3000 printed books
Find: in the 24000 books, the total number of books that will have a printing error
Solution:
Based from the given, we need to know how many sets of 3000 we
have in the 24000 books so:
24000 / 3000 = 8
Now, in each set of 3000 we have between 3 and 4 errors and we have 8 sets of 3000 books:
minimum errors 3 * 8 = 24
maximum errors 4 * 8 = 32
Therefore, at this rate, the number of books that will have a printing error in the 24000
will be between 24 and 32 or 24 < E < 32.
