Done, and also changed the tolerance of the example test cases to +/- 1e-8 as it was still the 0.01 as in the old version. Thank you

Thank you!

Thanks for the input, I've added more fixed tests and more random tests. I will mark the issue as resolved now.

Agreed. I changed the tests to tolerate erros of +/- 1e-8.

I am not sure I understand the issue here, I tried running your code and I noticed it passes when (1, 5) and (1, 2) fail to show up in the random test cases for some reason.

I have now added these two test cases to the fixed "advanced tests" to make sure they always show up.

Does this solve the issue?

A probability can be expressed as a number between 0 and 1, a fraction or a percentage.

Ok, thanks for the heads-up!

I did, honestly I just haven't worked out how to do it yet :D any good pointers? Sorry I am still learning about testing!
