A bag of coins contains 2 quarters, 5 dimes, 3 nickels, and 4 pennies. If 2 coins are randomly chosen from the bag, one after the other, and not replaced, and if the total value of the chosen coins is 26 cents, what is the probability that a third coin randomly chosen from the bag will be a penny?

Can you first make a sample set of the coins needed to make it to 26 cents?

You'll find out that it's only 1 quarter and 1 penny that can make 26 cents. From here you need to change the total value and then just find the probability of a penny. I think you can do that.
