Question 855718: Six slips of paper with the numbers 6 through 11 are placed in a box. After mixing well, two slips are drawn. List the different combinations formatted as ordered pairs.
Answer by ramkikk66(644)   (Show Source):
You can put this solution on YOUR website! The combinations would be:
(6,7), (6,8), (6,9), (6,10), (6,11)
(7,8), (7,9), (7,10), (7,11) ---> Note that you don't include 7,6 since it is already counted. 6,7 and 7,6 are equivalent.
(8,9) .... through till ...(8,11)
(9,...)
(10,...)
You can fill in the rest! You will get a total of 15 ordered pairs.
Hope you got the idea :)
