Bascule is reading a book.
What is the probability that the first digit of the page he is on is 1, 2, 3, 4 or 5?
a) obtain an expression
b) approximate a numerical value

First Steps? by TomM)
You also need some probability distribution over the number of pages in a book. In this case, p(n) would define the probability that Bascule is reading an n-page book. You can define a function f(n) which calculates the probability that the page number begins with 1, 2, 3, 4, or 5 for a book with n pages. The complete solution would be a summation of p(n) f(n) over all possible values of n.
