What books would you recommend for someone with a **bio** and not **maths** background to learn about probability distributions?

I am looking for something that could be easily related to bioinformatics as I work in Human Population Genetics.

Any (free) online courses or good web tutorials are very welcome as well!

Thank you!
Since you're in the UK, you should check [your favourite bay for second hand things] for the OU courses M248 and subsequently, M343. These will give you a pretty broad intro to probability models and a little bit of statistics (from the former). The latter might get a bit mathematical for you (at the moment). Since you're posting on here, you might be best served by getting [Ewens and Grant][1]
