The mother asks each boy to draw a card and after each draw, the card is replaced back in the box. She shows some magic tricks and at the end, decides to test their mathematical skills.

If the card is not replaced after the second draw, the probability of drawing a card bearing a multiple of 3 greater than 4 in the third draw by the third boy is:
