How many trial picks expectedly sufficient to cover a sample space?
The r=1 case is just the coupon collector's problem - en.wikipedia.org/wiki/Coupon_collector%27s_problem. Look at the 'calculating the expectation' section of the linked page for a much simpler and more elegant way of getting your result. |

question on sigma-fields
Don't we need the sequence Y_n to converge to Y pointwise, not just almost surely, since we want Y = f(X) pointwise, not just almost surely? Of course, this isn't a problem for the proof, since such a sequence exists. Also, a way to avoid the distinction between when lim_n f_n exists and when it doesn't is to just take f = limsup_n f_n. |
