At a monthly meeting, 2/3 of the attendees were males and 3/4 of the male attendees arrived on time. If 5/6 of the female attendees arrived on time, what fraction of the attendees at the monthly meeting did not arrive on time? Choose the correct option:
A) 1/3
B) 1/4
C) 3/8
D) 2/9
E) 5/18
Males who did not arrive on time are 1/4*2/3 = 1/6 of the attendees.   Females who did not arrive on time are 1/6*1/3 = 1/18 of the attendees.   The fraction of all attendees who did not arrive on time is 1/6 + 1/18 = 2/9   The answer is 2/9.
