    No, it's 1/6; just multiply

    Tina and Karen are are among the 4 colleagues that can get an "X" office, 4 possibilities for each creates a total of 24 possibilities. Tine alone has two chances of getting an "X," and so does Karen thus creating a 4/24 possibility. Reducing would be 1/6, if I'm not mistaken -- mathematically speaking.

    there are two ways to assign Karen, Tina to the Xs (2! = 2) there are two ways to assign the others to the remaining squares (2! = 2) so there are four ways to assign them such that Karen, Tina get Xs there are twenty-four ways to assign them without any such constraints (4! = 24) so only 4/24 = 1/6 of these ways will assign Karen, Tina to the Xs

    I thought we weren't supposed to provide answers, but assist the asker in arriving at the answer themselves.

    I already knew the answer was 1/6 but I didn't know how to arrive at it.

    you knew about 1/6, but that could be a wrong answer even if you were told that it was the correct one. we prove in math, not pick up from someone's answer.
