Expectation of bernoulli trial

#1

As per wikipedia the expectation value is np where n is the number of trials but in the video it says 1/p. But many questions are being correctly solved by this concept. I’m unable to understand the difference

Hi

the expectation value is 1/p
: it is the expected number of attempts for the first success

please post the link of wiki on which you are seeing, it might be some other expectation value.

Hit like if you get it!
Cheers!

The link says the expected value for n trials as n*p. But i read that for geometric distribution the the number of trials before a succes in bernoulli trial is 1/p. I’m not able to distinguish the difference
