Empirical prob is the same as "experimental" which is obtained from collected data. So the prob of an "A" is 45/the total number of grades. Find the sum of the number of grades. Divide 45 by that number. OK?

The sum of the grades. Add all of the A's, B's, etc. That will be the Total number of grades for the three years. There were 45 "A"'s so then 45 divided by the total number of grades. OK?
