- Expected value of sums 9 answers
Suppose we have well shuffled standard deck of 52 cards. What would be the expected number of cards turned over without replacement until a spade is shown? The problem is easy if replacement is allowed, but I don't know how to setup a trial to take into account the conditionality of the probability. Solving the expected value problem recursively also doesn't work since there isn't replacement. Any tips on solving this kind of problem?
