If you have 3 quarters, 5 dimes, and 2 nickels in your pocket what is the probability you will pick a dime and then a quarter without putting the dime back in your pocket?

10 coins to start    5 dimes       5 out of 10 to pick a  dime first     5/10

9 coins left             3 quarters   3 out of 9  to pick a Q                   3/9

 

5/10  *  3/9  = 15/90 = 1/6
