Hmmmm.... The averaging makes me think of "expected values" in probability. So, if you stop at any particular point to check the partial sum, or if you are wondering whether the light it on or off at the end of 2 minutes, the "1/2" means that the probability of each answer is 1/2.
We haven't done the experiment yet, but we think the light will be on. (the majority of us that is). Thanks for commenting!-Grade 8,s
