We called State Ed and asked about this exact error (common enough that the
rubric should have directly addressed it.) Here's what they said:
-2 points for 3/18 and 12/18, conceptual error
BUT (I'm still scratching my head on this one)
-1 point for writing "3 out of 18" and "12 out of 18", in words but not in
fractions

Hm......sounds like a reading error to me...
if they said 3/18 doesn't that imply that the student KNEW that there were
THREE outfits? The fact that they stated extra information...that is there
were 3 out of 18 (3/18) doesn't mean they didn't understand the concept of
how many...clearly, they did if they got a 3 in their answer.

We gave 2 points - thought it was a conceptual error to write a probability
instead of how many

Question 38...What would give (2 points or 3 points)the question if the
student got the correct sample space but wrote the two anwers of 3 and 12 as
probabilities (3/18 and 12/18)?
