Question 1078996: Imagine that you are the one picking for the raffle draw of employees, the bowl contains papers with names of 10 employees from the purchasing department and 20 from the sales department. If you draw 4 prize winners, what is the probability picking all 4 people from the sales department? (Round off your answer in two decimal places) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 30 employees in all and 4 are going to win. 30C4 is the denominator.
20C4 is the numerator.
0.1768 or 0.18

a check would be 20/30*19/29*18/28*17/27=0.1768 or 0.18
