Eating zongzi on the Dragon Boat Festival is a traditional custom of the Chinese nation. On the morning of the fifth day of May, my mother prepared four zongzi for Lele: one stuffed with red bean paste, one stuffed with sausage, and two stuffed with assorted stuffing. The four zongzi are the same except for the different fillings inside. Lele likes to eat zongzi with assorted dumplings, so what is the probability that the two zongzi he eats happen to be assorted dumplings?
