&gt; &quot;and get the same (correct) response of 1&#x2F;3&quot;<p>Are you sure it&#x27;s the correct response?<p>The way I see it, the correct response is &#x27;neither&#x27;, i.e. neither 1&#x2F;3 or 1&#x2F;2. Without having any indication about how many times you have played the game, there is no way of determining between the two odds, it could be your first go, or it could be your 1 millionth go.<p>Without any knowledge of time spent, there is no correct answer other than &#x27;neither&#x27;.
