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)

R*F = 5LF, R*M = 9LM, L*F + L*M = 18, R*F + R*M = 122.
RF=50,
LF=10
, RM=72
, LM=8. Fill in the graph with this info and assume there aren't people that are transgender
