So you have 1 of each a penny a nickel a dime and a quarter so the number combos is shown below 1 penny and nickel 2 penny and dime 3 penny and quarter 4 nickel and dime 5 nickel and quarter 6 dime and quarter The reason why number 4 doesn't say nickel and penny is because is if I had said that it would of been the same as number 1 just that the penny and nickel has switched places so the number of different 2 coin sums are 6
also a penny + a nickel + a dime + a quarter is = to 41 cents
