Three kinds of toys, each 1 piece, were given to Yiyi Pingping and Tao Tao respectively, and there were 18 ways to give them away. According to relevant data, there are/kloc-0 pieces of three kinds of toys sent to Yi Yiping and Tao Tao respectively, which can be solved by mathematical probability. The setting is that Yi Yi takes toy A, Pingping can only take B or C, and Tao Tao can only choose the rest of Pingping. That is to say, when Yi Yi takes one, there are two distribution methods. And one * * * three kinds of toys, there are three people, that is, 2 times 3 times 3 equals 18 kinds of delivery methods.
