Probability: 11 out of 29; or 37.9310345%. Method: Take a sample of 100. 45 are men; 40% or 18 men wear glasses 55 are women; 20% or 11 women wear glasses. So out of 100, 18+11=29 wear glasses out of which 11 are women. Probability: 11 out of 29

math
-1/2, 1/7, 2/7, 6/7 Method: Negative (-1/2)is obviously smaller than positives. So that is the smallest. Then arrange the rest in order of the top (numerator), since the bottom (denominator) in each case is the same.
