The Attempt at a Solution
So I'm trying to answer the final q  what fraction stagger right through?
The answer I get is 1/16... is this right? It just seems quite small..
My reasoning was that the probability of getting through the first is 1/4 and then if its in the state 1,x> the probability of measuring 1,z> is also a quarter.. therefore it is 1/4 times 1/4 i.e. 1/16 right?
