I thought that W would be relevant because W choose X is the amount of all possible tests, and you would need to divide by this in the end to get the probability. Anyhow, it seems to me, that for Z≥Y (if Z<Y then the probability is 0) this probability would be: Z choose Y plus Z choose (Y+1)...

I really have no clue how to describe it. Never taken a probability course before.

As both of you said, I did try to find the probability of the negation and then doing 1 minus that. But I noticed that finding this probability is not anymore easier...
