"Exit" -- A router is called an 'Exit' iff it allows exits to at least one /8 address space on each of ports 80 and 443. (Up until Tor version 0.3.2, the flag was assigned if relays exit to at least two of the ports 80, 443, and 6667.)
Right. And see also my future plans to make it just "80 and 443": https://bugs.torproject.org/23637
The Exit probability is 0 without the Exit flag. 200 Exit connections without the Exit flag ? Seems ylto be weird...
I don't think it's that weird. You can read more about the goals of the Exit flag here: https://trac.torproject.org/projects/tor/ticket/22820#comment:3
but the simple summary here is that the Exit flag, and thus the exit probability, is about *load balancing*, so other clients can choose their paths in a way that produces globally useful choices.
That is, think of an exit probability of 0% as saying "Other people should assume that I am not using any of my bandwidth for exit streams, so I am fully available for use in other circuit positions", not "there is no chance that you can exit from my relay".
