You have to find the probability of pull a silver coin out of both bags separately
To do this you do the most favorable outcome over the total amount of outcomes ------------------------------------------------------------------------------------------------------ Bag 1 The first bag has 1 silver coin and 14 total coins
This is a probability of 1/14 ------------------------------------------------------------------------------------------------------ Bag 2 The second bag has 2 silver coins and 12 total coins
This is a probability of 2/12 ------------------------------------------------------------------------------------------------------ Finding the answer
To get the answer you multiply the two probabilities together
1/14 * 2/12 = 1/84 ------------------------------------------------------------------------------------------------------ The answer is C) 1/84
