A population of 200 voters contains 78 Republicans, 120 Democrats, and 2 independents and members of other parties. A simple random sample of 20 voters will be drawn from this population. Consider repeatedly drawing simple random samples of size 20 from the population (taking each simple random sample from the full population of 200 voters). The expected value of the number of simple random samples of size 20 that must be drawn until (and including) the first sample that contains at least one voter who is neither a Democrat nor a Republican is?
