Homework Statement
I am so confused/lost with this problem because I don't know how to draw it out (table or tree diagram?) I can't figure out how to lay out all the combinations in a simple manner.Two couples, Mr and Mrs Jones and Mr and Mrs Smith play doubles in tennis. Each time they select the teams by placing all four names in a hat and randomly selecting two names. These two form one team and the remaining two form the other team.
WHat is the probabality of:
a)each wife partnering her husband
b)one male and one female on the team
c)the two men in one team and the two ladies in the other?
Homework Equations
table, tree diagram
The Attempt at a Solution
Okay, tried drawing a tree diagram but it didn't seem to work because I need groups of 2 teams and when I draw the diagram, there is only 1 team...so it won't work. I'm not sure how can I set the info out so that I can have "groups" of teams, rather than the probablity of picking individual "2 person teams".
