c****n 发帖数: 21367 | 1 given Z_i \in {0,1}^n, i = 1,2,...
p(Z_i) \neq 0 for all Z_i
find out the pdf of Y = Z_1\oplus Z_2\oplus ...
\oplus is bitwise XOR operator
and further, calculate the expectation of number of "1"s in Y
is it a uniform distribution or normal distribution?
would the expectation of number of "1"s in Y be n/2?
