Total number of person against(81+68)                       =149

Total number of person has no opinion(5+7)               =12

Total number of female(103+68+7)                             =183

Total number of male(72+81+5)                                  =158

Total number of person in issue(175+149+12)           =336

Probability of female                                                                         =183/336

Probability of female or favor the issue                                            =103/336

Probability of female or favor the issue(183/336+103/336)             =286/336=143/168
