comment expected number of shared 1s between two binary strings from a given set
Gerry Myerson: that means no two identical strings in the set. Andreas Blass: 2^N-K is a given set, meaning some binary strings are not available. That makes the probability of having 1 at i-th position is biased. For example, when K=0, it is 0.5 exactly. But, when K=2^N-2 and two remaining strings are 11110 11111, the probability of having one at 0,1,2,3 the position is 1.0, while 4th has 0.5.
