thank you! Found 2 solutions by richwmiller, Alan3354:Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! first draw has 4 possible outcomes
second draw has 3 possible outcomes
4*3=12
If you consider that a penny drawn first and a nickel drawn second is the same as a nickel drawn first and a penny drawn second then we have only 6 outcomes.
You can put this solution on YOUR website! The 1st draw is 1 of 4.
The 2nd draw is 1 of 3.
3*4 = 12
But, a nickel and a dime is the same as a dime and a nickel, so divide by 2.
--> 6
