A hungry rat in an operant chamber has two available levers to press to earn food on a concurrent schedule. The left lever earns reinforcement on a VI-30 second schedule. The right lever earns reinforcement on a VI-10 second schedule. Assume the rat gets all of the reinforcers and there are 100 total lever presses in 10 minutes. How many lever presses will there be to the left and right levers respectively.
