russian roulette

[poker1O1]

ok, so this should be an easy one for you guys. say you and one other person play russian roulette, switching after each trigger pull. the revolver can hold 6 bullets, but only contains one bullet. it is not spun inbetween trigger pulls. my question is, can you show me the odds of getting shot if you go first? second? (I assume both are 50%) For whatever reason I cannot reach an answer
