The expected value require a sample space and a probability distribution associated with each outcome. The expected value of a random variable is the some of all possible values of the random variable weighted by the probability of it's occurrence. If success is a random variable, then that is how you would compute it.

Yes and just adding to the answer....In case you don't have probability distribution...you repeat experiment for a large number of times (infinite theoretically) to find probability distribution for each outcome
