If you have a geometric random variable with probability mass function:(adsbygoogle = window.adsbygoogle || []).push({});

P(X=n) = p(1-p)^n n = 0,1,2,3....

Find the Mean and the Variance.

----------------------------

Okay, ive looked everywhere and tried everything, however, i just cannot get it.

i think that your supposed to find the sum of this sequence to find the mean. I tried everything. I just tried the integral test. Anybody got any ideas?
