A large pile of coins consists of pennies, nickels, dimes, and quarters (at least 20 of each). (a) How many different collections of 20 coins can be chosen? (Assume that we can't tell coins of the same type apart: i.e. I can't tell the difference between two nickels. However, I can tell the difference between a nickel and a dime)
