• since survey refers to prior to graduation,

answer is 0% for question a)

• Add up the number of White candidates .. W

Add up the TOTAL number of candidates .. White + Minority .. T

Then it's W/T * 100

• Total Graduates

195+38+16+17+19+48+9+4+3+5 = 354

White Graduates

195+38+16+17+19 = 285

-------------------

% white = 285/354 * 100 = 80.5

80.5% <––––––

• Just add up all the numbers = total number of graduates.

Add up the numbers under whites = white graduates.

Total number of whites divided by the total number of students equals the percentage of the graduating class who are whites.
