Homework Statement
say i have fifty keys and 1 is the correct key.With replacement i can modell this as a geometric distribution to find the expectation of the number of bernouli trials required until i pick the correct key.But if there is no replacemnt then the probabilities change so how do i model this scenario in order to find quantities such as expoectation and variance?
we are asked to find the expectation when the keys are replaced and then the keys are not replaced. I have done the first bit but can't figure out the second when there is no replacement.
