Determine the probabiliy that the first 0 occurs as the fifth random digit generated?

so the probability of not getting a zero for the first four time is 9/10. then the probability of getting a zero for the fifth time is 1/10. and i just multiply that right.

how many digits would you expect to have to generate in order to observe the first o.

please help me. am i doing this right?
