Suppose you have pennies, nickels, and dimes in your pocket. if you pull out four coins, what possible amount of money could you get? how many different amounts?

Well first we need to know how many pennies, nickles, and dimes there are.

First, it all depends on how much money is in the pocket. You would add all of the money up and divide by how much there is then, change that into a fraction.. Then you would get your answer. For example lets say yo have a pocket with 5 pennies, 8 nickels, and 3 dimes. You add up the amount of coins, which is 16 coins. You pull out 4 coins, there is a 3/16 chance you would get 3 dimes.
Hope i helped.
