When you mix 50 ml of a substance with another 50 ml of the same substance, the molecules of the two substances occupy the same space, leading to a slight increase in volume due to the spaces between the molecules. This phenomenon is known as the "packing effect" or "intermolecular space," which causes the total volume to be slightly more than 100 ml. Therefore, 50 ml plus 50 ml does not equal exactly 100 ml due to this increase in volume caused by the packing effect. **

Additionally, the element of human psychology and decision-making adds an unpredictable factor to the game, making it impossible to achieve complete perfection. **
