To find the probability of a student who slept 6 hours or less and does not have an A, we need to look at the students who slept 6 hours or less and do not have an A. In this case, the number of students who slept 6 hours or less and do not have an A is 14.

The total number of students who slept 6 hours or less is 4 + 14 = 18.

So, the probability of selecting a student who slept 6 hours or less and does not have an A is 14/18 = 7/9.
