Given that total number of books in the book store = 75972
Given that total number of books in science section = rd of total books =
= 25324
Then remaining number of books = 75972 - 25324 = 50648
Given that 75% of the remaining books are in business section = 75% of 50648 = 0.75*50648 = 37986
Then number of books in the math section = 50648 - 37986 = 12662
Hence final answer is 12662 books in the math section.

P(X=1) = 1/36
P(X=2) = 3/36 = 1/12
P(X=3) = 5/36
P(X=4) = 7/36
P(X=5) = 9/36 = ¼
P(X=6) = 11/36

7/36
Step-by-step explanation:
1-
Attached, you will find a table with the possible values of X.
(See table attached)
As we can see, there are 36 entries so,
<em>P(X=1) = 1/36 </em>
<em> </em>
<em>P(X=2) = 3/36 = 1/12 </em>
<em> </em>
<em>P(X=3) = 5/36 </em>
<em> </em>
<em>P(X=4) = 7/36 </em>
<em> </em>
<em>P(X=5) = 9/36 = ¼ </em>
<em> </em>
<em>P(X=6) = 11/36 </em>
2-
It can be noticed that the only possible value of X which is divisible by 4 is 4 and there are 7 entries in the table, so
P(X divisible by 4) = P(X=4) = 7/36
