Question 354215
Total no. of person = 253         i.e n(s)

A. Solution: 

 no. of adults who prefer watching opera = 27 + 91 = 118

 probability of prefer watching opera =  118/253

= 0.466

....................................................................

B. solution: 

no. of male = 93 + 27 = 120

probability of male = 120/253

= 0.474

........................................................................

C. solution: 

no. of female = 42 + 91 = 133

no. of female prefer watching sports = 42

probability of prefer watching sports if female = 42 / 133


= 0.3158
.........................................................................

D. solution

no. of adults watching sports = 93 + 42 = 135

no. of male watching sports = 93

probability of male if watching sports = 93/135

= 0.68888

..........................................................................


E. solution:

no. of females watching opera = 91

probability of female that watching opera = 91/ 253 


= 0.35968



..........................................................................

F.   no. of adult who are  male or watching sport  = 93+ 27 +42 =  162  


probability of male or watching sport =  162/253


=  0.6403
