You can pull 4 people out of the crowd in (50 x 49 x 48) = 117,600 ways.
But you'll find that every group of 4 people has been pulled in 24 different ways
at 24 different times during the selection process.
The number of different groups of 4 finalists is (50 x 49 x 48)/(4 x 3 x 2) = 117,600/24 = only 4,900.

How many ways can four finalist be selected from 50 contestants?
If order matters, 50x49x48x47 = 5,527,200. If the order doesn't matter (which it probably doesn't, given that we're not selecting the winner, first runner-up, etc. directly), it's slightly trickier: there are 4!, or 24, ways of arranging four items, so we have to divide the larger number by 24 to get 230,300.
