Question 49609:
Suppose that you have thirty-five coins and nine pockets. Can you have a different number of coins in each pocket? (One pocket can have no coins.)
Mary typed a six-digit number, but the two 1's she typed did not show. What appeared instead was 2002. How many different six-digit numbers could she have typed?
