A gumball machine contains 25 gumballs - 9 red, 6 blue, 7 green and 3 yellow. You buy five gumballs from the machine.
X = number of green gumballs you get
-----
P(0 green) = 18C5/25C5 = 0.1613
---
P(1 green) = [7C1*18C4]/25C5
---
P(2 green) = [7C2*18C3]/25C5
---
P(3 green) = [7C3*18C2]/25C5
---
P(4 green) = [7C4*18C1]/25C5
---
P(5 green) = [7C5*18C2]/25C5
