A. 300 B. 450 C. 600 D. 800 E. 900 Let total attendees be x. Total Female attendees = 2x/3; Female Students = x/6; So Females which are not student are = x/2; Total Attendees x; Total students = x/3; So Non students = 2x/3; Females which are not students + Attendees which are neither females nor students = Total attendees which are not student. x/2+150 = 2x/3; x= 900 E.

I did it this way and got the answer
P(FUS) = P(F) + P(S)  P(FNS) x  150 = 2/3x + 1/3x  1/6x x  150 = 5/6x x = 150(6) x = 900
Therefore, answer is E.

A. 300 B. 450 C. 600 D. 800 E. 900 We will use the overlapping sets formula, which is: #(attendees) = #(female) + #(student)  #(both female and student) + #(neither female nor student). Let’s denote the total number of attendees by x, i.e., #(attendees) = x. Since 150 of the attendees are neither female nor student, #(neither female nor student) = 150. Since 1/6 of the attendees are female students, #(both female and student) = (1/6)x. Since 2/3 of the attendees are female, #(female) = (2/3)x. Since 1/3 of the attendees are students, #(students) = (1/3)x. Let’s plug in each of the above into the formula: x = (2/3)x + (1/3)x  (1/6)x + 150 x = x  (1/6)x + 150 (1/6)x = 150 x = 900 Answer: E
