You can put this solution on YOUR website! From a bag containing 6 nickels,10 dimes,and 4 quarters,6 coins are drawn at random all at once. What is the probability of getting 3 nickels,2 dimes, and 1 quarter?
-------------------------
# of ways to get 3 nick, 2 dimes and 1 quarter:
6C3 * 10C2 * 4C1 = 3600
----
# of ways to randomly select 6 coins from 20 = 38760
---
P(3 nick and 2 dimes and 1 quarter) = 3600/38760 = 0.0929
