1.There are p kinds of objects with four of each kind and q kinds of objects with two of each kind (q is an even number). In how many ways can they be divided into two equal piles such that there is an even number of each kind of object in both piles ?(0 is taken as an even number .) Evaluate your result for p=4 and q=2. 2.(a)Find the ordinary generating function of the sequence (a0,a1,a2...) where ar is the number of ways of selecting r objects from a set of six distinct objects , where each object can be selected no more than thrive. (b)From the generating function found in part (a) ,determine the number of outcomes when three indistinguishable dice are rolled -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.216.145
