I am stuck on this question any help would me much appreciated:
Consider asequence of bernoulli trials with probability of success p. Let random variable X be the number of trials needed to get the 1st success.
Is the state space of random variable X [success,failure]?
What would be the probability distribution of X?
What's the mean value of X?
