Prob of just quarter is 3/14 for a dime is 4/14 and for a nickel its 7/14
then all you do is multiply them all together to get 306122449/<span>10000000000 that took me way to long</span>

How I did it:

I did 3/13, and got 0.23, I didn't do 14 because if its going to be chosen, its going to have one less, and I did the same for the other ones. Then I simply just multiplied them.
