Sounds like a hypergeo
But it seems that you want the distribution of the number of bad tvs selected
where x=0,1,...9.
That took forever to type on a lame ipad with a lousy connection at an airport.
Tv's are manufactured in lots of 200, 9 of these are tested and if none are faulty then the lot is accepted, find the probability distribution of the number of faulty televisions assuming there are 20 in a lot.
Help :/ Is this the poisson distribution?
