At a job interview, your potential employer presents you with the following test:

There are 2 buckets, and a bin with 50 green balls and 50 red balls.
He tells you he will leave the room, and that you must place the balls in the buckets.
When he comes back, he will randomly select a bucket (with equal probability), and randomly draw a ball from that bucket.
If he draws a green ball, you are hired.

Rules:
I. No bucket can be empty
II. Each of the 100 balls must be placed in one of the two buckets

What do you do?
