The negative binomial distribution is the one which best describes this problem.

This probability measures the probability of needing X trials to obtain r sucesses with p probability.

The mean value is given by

Here, for example, we want 2 sucesses with 0.2 probability. So

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km
