Recall that a 5-bit string is a bit strings of length 5, and a bit string of weight 3, say, is one with exactly three 1's. How many 5-bit strings are there? How many 5-bit strings have weight 0? How many 5-bit strings have weight 1? How many 5-bit strings have weight 2? How many 5-bit strings have weight 4? How many 5-bit strings have weight 5? How many 5-bit strings have weight 11?
