Consider a sequence of independent Bernoulli trials with p= 0.2
a) what is the expected number of trials to obtain the first success?
for this I thought of it as geometric so 5 trials
b) after the eighth success occurs, what is the expected number of trials to obtain the ninth success?
I don't know how to go about this one?
