Solution: (1) This is a typical Bernoulli misinformation problem. You can analyze it this way, for example, if you give A first, then A has three possibilities. Then there are two situations for the person whose ticket is taken away by the next person. First, there is only one way to get tickets; Second, there are two ways to get tickets from people other than A, so there are 3× (1+2) = 9 kinds of * * *.

(2) If any element in N has an original image, first remove two elements from M and put them into N respectively. It is possible in A (7 below, 2 above). There are three possibilities for the remaining five. So the total * * * is 7× 6× 3 5 = 10206.
