Explanation:
In this case the balloon will burst and helium will spread in jar . It will happen because after evaculation of air there will be no air and due to the lake of air and its pressure the balloon will feel more pressure inside the wall so in that case the helium inside the balloon will put more pressure on the wall of balloon and balloon will burst or explode.
