Answer:

0.25 or 1/4

Explanation:

Probability is calculated by the item you are looking for divided by all the items in the list.

In this case you should divide the number of math-history books to all the other books in the bookshelf.

[tex]\frac{2}{8} = \frac{1}{4}[/tex]

The probability of choosing a math-history book is P = 2/9.

How to get the probability?

We know that there are:

  • 2 math-history books.
  • 3 books of statistics.
  • 2 books of number theory.
  • 2 books of geometry.

So there is a total of 9 books. Assuming that all the books have the same probability of being randomly picked, the probability of choosing a math-history book is equal to the quotient between the number of math-history books and the total number of books, so we have:

P = 2/9
