at a monthly meeting , 3 / 5 of the attendees were males and 7 / 8 of the male attendees arrived on time . if 4 / 5 of the female attendees arrived on time , what fraction of the attendees at the monthly meeting did not arrive on time ?
n0 = 3.0
n1 = 5.0
n2 = 7.0
n3 = 8.0
n4 = 4.0
n5 = 5.0
t0 = n4 / n5
t1 = n0 / n1
t2 = n2 / n3
t3 = 1.0 - t0
t4 = 1.0 - t1
t5 = 1.0 - t2
t6 = t3 * t4
t7 = t1 * t5
answer = t6 + t7
