    No student will receive this grade!

    Seriously, you probably mean
    "a grade less than 58 or greater thAN 110 "

    What can be done is to calculate the percentage of students who receive X, where 58≤X≤110.

    Given μ=85, σ=8, then
    From Z(58) and Z(110), find the percentage of students in this range using the normal distribution table.

    Finally, subtract this percentage from 100 to get the students outside of this range.
