The first minute (Starting at 12 noon), 1 person came and put in a ball. The second minute, 2 people put in one ball a piece. A minute later, 4 people put in 1 ball a piece. This pattern continued until the bin was exactly full at 6 pm. At what time was the bin half empty?

5:59 since the bin's balls double every minute.

It's never EXACTLY half-full. The closest it will come is 5:59pm, but at that point, it will be approximately 1 short of being half-full, since the correct "full" amount is an odd number.
To sum up, the CLOSEST you can come is 5:59pm.

I would say 3:00 p.m. Because if it was "full" at 6:00 p.m. then 1/2 of that is 3:00.
