Question 1196647
.


Hello,  the normal distribution curve is symmetrical relative to the mean score.


THEREFORE,  the percent of scores above  110  is  50%  in this problem.



It is clear  (and should be clear)  without any calculations.



By the way,  for your better understanding,  when they ask you about the percent above some score, 


it means that you should find the  AREA  UNDER  normal curve to the right of the given score.



There is nice online calculator for solving such problems under this link


https://onlinestatbook.com/2/calculators/normal_dist.html



It is for common use and is free of charge.


It provides an accompanying plot,  shoving which area under the normal curve is of your interest.

It prevents you of making errors.


This calculator is  {{{highlight(highlight(indispensable))}}}  teaching tool for you,  when you make your first steps in such calculations.



So,  play with it as much until you learn the subject sufficiently.
