AND ITS SUPPOSED TO BE A FRACTION​

There is a 4/12 or 1/3 percent that I would get a Canadian currency nickel and a 1/12 percent that it would be a USA nickel. For how I got the 4/12 fraction, I just add all the coins together and see how much nickels are from Canadian currency and then that will be the fraction. Since there is only one nickel that is from USA out of 12, then it‘ll be 1/12 as the fraction.
