Flamingos Fanny and Freddy have three offspring: Happy, Glee, and Joy. These five flamingos are to be distributed to seven different zoos so that no zoo gets both a parent and a child :(. It is not required that every zoo gets a flamingo. In how many different ways can this be done? here if i am using case method on children i am getting a different answer than when i am using case methon on parents, why is that?

how many ways can we form a team of 2 men and 2 women such that no couple is a part of team ?
There are 10 couples at party .In this question I have only doubt that if I chose 2 husbands first ,now for wives remaining choice will be 8 so it will be 10C2 *8C2 ,Now I could have done it other way around ... no of ways in which team can be formed is 10C2*8C2 ,now why can't we add these two cases ?
