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

WebFeb 15, 2024 · How many bit strings of length 8 have an equal number of 0’s and 1’S? Solution: You are choosing from a set of eight symbols {1, 1, 1, 1, 0, 0, 0, 0} (which would normally give 8! = 40320 choices, but you have three identical “1″s and three identical “0”s so that reduces the number of options to = = 70 bit- strings. Similar Problems ... WebMay 4, 2024 · Or, for maybe slightly less computation, you could say "at least 3" means not ( 0, 1, or 2 ), so (since there are 2 7 bit-strings of length 7 in all) 2 7 − ( ( 7 0) + ( 7 1) + ( 7 2)) = 99. Of course, if you've already calculated 64 for "at most 3 " and 35 for "exactly 3", you can say "less than 3 " is 64 − 35 = 29 so "at least 3 " is 2 7 ...
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. http://math.utep.edu/faculty/cmmundy/Math%202400/Exams/Some%20practice%20exam%202%20solutions.pdf
