WebThe binary digits are simply the numbers 0 and 1. All of the following are bit strings: . 1001 0 1111 1010101010. 🔗 The number of bits (0's or 1's) in the string is the length of the string; the strings above have lengths 4, 1, 4, and 10 respectively. We also can ask how many of … WebThese 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. Copyright © Peter Cappello * 20 (b) How many bit strings of length 10 have more 0s than 1s?

WebJul 15, 2015 · How many bit strings contain exactly eight 0s and 10 1s if every 0 must be immediately followed by a 1? I got answer 9C2=36.Answer given 45 ... the bit strings must consist of eight 01 substrings and two 1s. Thus, there are ten total positions and choosing the two positions for the 1s determines the string. WebThe number of 15-bit strings that contain exactly seven 1's equals the number of ways to choose the positions for the 1's in the string, namely, (b) How many 13-bit strings contain at least ten 1's?
