1/6 = female students
4/6 = female
2/6 = students

(4/6+2/6) = 6/6 - (1/6) = 5/6 (add two groups together and subtract out their shared amount)

5/6 are females OR students, if 150 are neither then 150 = 1/6 of attendees

Total = E. 900 attendees

X is the total students

x = (2x/3) + (x/3) -( x/6) +150

x=900

You can solve it faster by drawing Venn Diagram.
