At the eve of marriage anniversary of Tristan and lseult some special couples were invited. Out of them only 23 couples were there having one child per couple with them. When I observed it, I found that 13 men were without any child and 20 women were also without any child. It is known that there were only couples allowed to attend the ceremony. For your kind information we will not consider the couple (i.e., Tristan and Iseult) for any calculation, since they are hosts. The total number of couples who attended the party (i.e., anniversary).
