    I think the state space is {0 ,1,2,3......} because this is the number of trials needed to get the first success?




    P{Xn=1} = p
    P{Xn=0} = q

    i think again??



    and for c is it something to do with teh sum of between 1 and 0 nCn P^x(1-p)1-x?

    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?
    Research the geometric distribution.
