Exploring Quantum Physics - Final Exam Part 2 Question 1

Question:

Given:

s3|=2| and s3|=2|

Find

s312(|↑↓|↓↑)

Solution:

Disclaimer: My answer is wrong.

It seems to be a really simple question, just apply the definitions.

s312(|↑↓|↓↑)=12s3[||,||]=12[|2+2|,2|2|]=212[|+|,||]

Now I am stuck, it appears the vector I get is not in the choices. For the exam, I guessed an answer, and got the wrong answer.
