higher floor chosen at random. What is the expected number of stops the elevator makes? Generalize the

result for a k -store building with k>2: Estimate the value k0 such that the probability that the elevator

will stop exactly 10 times is larger equal than 0.9 for all k>k0.

I've done this so far not sure if it is correct

the Expectation of number of stops = 7 . (1-(6/7)^10)= 5.5
