Note: Recall that set S itself cannot have repeated elements. A set in which some elements are repeated is called a multiset. Note: Two permutations of the same set are distinct if order of

http://mason.gmu.edu/~jsuh4/impact/Handshake_Problem%20teaching.pdf WebThe handshaking theory states that the sum of degree of all the vertices for a graph will be double the number of edges contained by that graph. The symbolic representation of handshaking theory is described as follows: 'd' is used to indicate the degree of the vertex. 'v' is used to indicate the vertex. 'e' is used to indicate the edges. Web1 Answer Sorted by: 3 I think a simple matrix is the best way of looking at this problem. Each element of this 20x20 matrix is =1 if two people (i,j) shake hands. Clearly for any two people (i,j) you need to cound the handshake only once and (i,i) is also clearly not allowed. bytbasics
