Ireally don't know how to do there are 5 times as many right- handed female students as there are left-handed female students, and there are 9 times as many right-handed male students as there are left-handed students. if there is a total of 18 left-handed students and 122 right handed students in the school, which of the following is the closest to the probability that a right-handed student selected at random is female? (assume that none of the eight-grade students are both right-handed and left-handed)
