A spider eats 3 flies a day. Until the spider fills his quota a fly has a 50% chance of survival if he attempts to pass the web.

Assuming 5 flies have already made the attempt to pass, what is the probability that the 6th fly will survive the attempt?

(In reply to Easier than it sounds... by Magick321)

'the previous flies cannot and will not affect the sixth's chances... '
They do.
You're wrong.
