Probability Calculator test faild

Hi,
Can somebody help me with my Probability Calculator? It fails in the test module first test (expected around 0.272, my prob. 0.117), everything else looks good. I am new at programming, and I know my code is a little messy, and I could have used the class for the experiment, It seemed easier for me, maybe because at that time I did not totally understand the task. :grimacing: I tried hundreds of version in last days to make it work, but I have to admit , the probability to solve this by myself is as low as my test provability result :sweat_smile: Can somebody look at it, do I have to rewrite the whole experiment function, or is something what I can do to make this work?
Thank you for your time!

My code is here.

I completely rewrote the second part and now it’s working.
