Let X and Y be the following sets: = {15, 9, 11}
y = {11,9,2}
Which of the following is the set XY?

the answer is 8/21

hope this

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
