I choose a random sample of 5 of 20 sofas and I find that all of them are more than $400. If only 10 of these sofas were supposed to be more than $400, what is the probability I would get 5 costing more than $400 in my sample of 5? What would that probability be if 11 of the sofas cost more than $400? Or 12 sofas costing more than $400?
