The bounce rate has a very loose relationship to the number of pages viewed on a visit.
Suppose a website has a bounce rate of 40%. What is the range of possible values for the average number of pages viewed per visit?
60% of visitors viewed only one page, and the rest viewed at least two pages. There is no limit - except the number of pages on the website - to how many pages a visitor can visit. All of the 60% of non bounce visitors could have viewed either 2 pages, or all the pages.
The smallest average number of pages viewed per visitor is
\[0.4 \times 1 + 0.6 \times 2 =1.6\]
The largest possible number of pages viewed per visitor is
\[0.4 \times 1 + 0.6 \times \infty = \infty\]
