comment Expectation of an event
Thanks for the solution. It works nicely. Just one quarry. In the recursive formula of $E[k]$, why did you add 1? That is $E[k]=1 + \ldots$.

comment Expectation of an event
I take three random integer r,s,t in [1,1000] with replacement. And 1. Set A[r]=1 2. Set A[s]=1 if A[t]=0 3. A[t]=1 if A[s]=0.

Thanks for LaTeX. Yes, identity or zero matrix satisfies the condition but I want to find general form.
