How many 8-bit strings contain 7 or more 1's

Web(b) How many bit strings of length 8 contain at least 3 ones and 3 zeros? Expert's answer a) We need to consider 3 different cases. Case 1: there are six 1s. C (8, 6)=\dbinom {8} {6} C (8,6) = (68) Case 2: there are seven 1s. C (7, 6)=\dbinom {8} {7} C (7,6) = (78) Case 3: there are eight 1s. C (8, 8)=\dbinom {8} {8} C (8,8) = (88) WebA bit string with exactly 3 0s can be described as a 3-subset of the numbers 1, 2, …, 10. These are the bit positions where the 0s go. There are C(10, 3) such 3-subsets. For each such 3-subset, all other positions take 1s. There is 1 way to do that. The answer thus is C(10, 3) = 10 . 9 . 8 / 3 . 2 . 1 = 120.
