Question 970696
A piggy bank contains 5 dimes, 6 nickels and 9 quarters. If you draw out two coins, what is the probability of drawing a dime and a nickel if the coin is not replaced?
----
# of dime/nickel pairs:: 5*6 = 30
# of random pairs:: 20C2 = 19*10 = 190
-----
P(draw dime/nickel pair) = 30/190 = 3/19
