    3/6 * 2/5= 1/2 * 2/5= 2/10 = 1/5

    well first you find how many coins there are in all. In this problem the entire amount is 6 coins,
    3 of the 6 coins are dimes,
    if you pull out one dime there are now 2 dimes out of 5 coins ( because you took one away)
    so the answer would be two out of five chances.
