**MathMate**, Monday, September 10, 2012 at 8:36am"a grade less than 58 and greater thAN 110 "

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

Z(X)=(X-μ)/σ

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.
