During the course of a Friday night, a nightclub often receivessome counterfeit ten-dollar bills. At one point in the night, thereare two counterfeit ten-dollar bills randomly distributed in astack of a total of 8 ten-dollar bills (counterfeit and legitimate)in the cash register. From that point on, no additional ten-dollarbills are received, they are only paid out from the top as a changeto patrons of the nightclub. What is the probability that thenightclub will have no counterfeit ten-dollar bills in its cashregister if only 4 ten-dollar bills are paid out during thenight?
