30% of the students taking algebra also take trigonometry and 50% taking trigonometry also take algebra. if 36 students take both subjects, how many students take only one of the two? please explain! thanks! <3
if 70%(.7*36=25.2) students take one and .5 of students take one or the other (.5*25.2=12.6) app=13 students
the answer is supposed to be 120 :o
