#### Question

A book contains 85 pages. A page is chosen at random. What is the probability that the sum of the digits on the page is 8?

#### Solution

Number of pages in the book =85

Number of possible outcomes=n(s)=85

out of 85 pages, pages that sum up to 8= {8,17,26,35,44,53,62,71,80}

pages that sum up to 8=n(E)=9

Probability of choosing a page with the sum of digits on the page equal 8= `(n(E))/(n(s))=9/85`
