You know how the fill tool in Paint works. If you have a really large computer screen (a billion pixels, say) and you fill each pixel in the screen randomly either black or white (equal probability either one), what is the average number of times you would have to use the fill command for turning black pixels white to then turn the entire screen white?
I just thought this up a little while ago and I have no idea how to do it except empirically. Is this a solved problem?
