WebMay 1, 2012 · If N is 1, the only possible strings are 0 and 1, so there's a 50% chance that X is odd. The possible strings when N=2 are the strings of N=1 with either 0 or 1 … WebHow many bit strings of length 10 both begin and end with 1? n. How many bit strings with length not exceeding n, where n is a positive integer, consist entirely of 1s, not counting the empty string? 26+26²+26³+26⁴ = 475,254.
WebThe first question may have been about strings of length up to n. It is certainly true that the empty string has no bits which are not 1. For the second I would give the answer 0 for n = 0 and the answer 1 for n = 1, as I would argue that the single bit string 1 both starts and ends with a 1 and so should be counted. Share Cite Follow WebFor a random bit string of length n find the expected value of a random function X that counts the number of pairs of consecutive zeroes. For example X ( 00100 ) = 2 , X ( 00000 ) = 4 , X ( 10101 ) = 0 , X ( 00010 ) = 2 .
