Answer: The average number of books in each mmonth is 4.
Explanation:
Since we have given that
Numbers of books in 6 months are as follows :
3, 5, 4, 5, 2, and 5.
Number of months = 6
We need to find the average.
Average is given by
(3+5+4+5+2+5)÷6
= 24 ÷ 6
= 4
Hence, the average number of books in each month is 4.
