Recall that a 6-bit string is a bit strings of length 6, and a bit string of weight 3, say, is one with exactly three 1’s. How many 6-bit strings are there? How many 6-bit strings have weight 0? How many 6-bit strings have weight 1? How many 6-bit strings have weight 3? How many 6-bit strings have weight 5? How many 6-bit strings have weight 6? How many 6-bit strings have weight 10?
