Yes, technically the function that is being integrated should be positive in the integration domain for the comparison test.

Why would anyone need to do this? Perhaps you could provide a link to some reference? Also, could you explain the usage of "|" symbol in definition? What does it signify? Or is it interchangeable with ","?

If probability of a success is 0.3 what is the expected number of failures? Binomial distribution: E[X] = np, if E[X] = 3 and p = 0.3 we get n=10 and the number of failures is 10-3=7. Isn't it strange that this gives the same answer even if this is not in binomial distribution (as far as I understand)? Jun 12 comment Bernoulli trials are run until 3 successful trials are completed. If probability of a success is 0.3 what is the expected number of failures? But I am aware of Pascal's distribution which looks similar to NB. Using that I get that E[x]=n*0.3/0.7 = 3 => n=7. So the number of failures is 7-3=4?
