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.

WebQ: How many bit strings of length 10 either begin with three 0s or end with two 0s? A: Click to see the answer. Q: How many bits string of length 4 are possible such that they contain 2 ones and 2 zeroes? A: 2. Given Data: The length of string is: n=4 The number of ones is: 2 The number of zeros is: 2 The…. Webstring are numbered from zero up to the number of bits in the string less one, in right to left order, (the rightmost bit is numbered zero). When you convert from a bit string to an integer, the zero-th bit is associated with the zero-th power of two, the first bit is associated with the first power, and so on. fishtail braid hairstyles tutorial
Solved How many 8-bit strings contain 7 or more 1
WebHow many 8-bit strings have at least one 1? Answer = 28- 1 = total # of 8-bit strings minus the # of 8-bit strings with no 1's How many 8-bit strings read the same from either end? Answer : Since the strings read the same from either end, this means that the first 4 bits of the 8-bits string uniquely determine the string! So, how many WebQ: How many bits does the binary expansion 10500 have? A: It is known that the formula for the number of bits in a number is given by, Q: How many 10-digit binary strings have an even number of 1's? A: 10-digits binary string can be: {1010101010} Even number of 1's means the number of 1's can be…. 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. fishtail braid bridal hair
