I think I can do a few, GM

 

a)  P ( UF l UT)  =  86 / ( 77 + 87 + 86)   =  86  / 250  =  43 / 125

 

b)  P ( UF  or UT)  = P ( UF U UT)  =   P(UF)  + P( UT)  - P(UF   ∩  UT)  =

     

                                                   (86 + 21)          250          86             21  + 250            271

                                                  ________  +   _____  -   _____  =    _________ =      ____

                                                     300               300           300             300                   300

 

c)  P (UF  and UT )  =   P(UF  ∩ UT)  =    86/300  =  43/150

 

d)  P(UF)   =   (86 + 21)  / 300  =    107 / 300

 

e) P (UT)  =  (250)/300  =  25/30  =  5/6

 

f)  P ( UT l UF )    =  86  / (86 + 21)  =   86 / 107

 

g)  It appears  that  the greater one's math skills, the less one supports capital punishment

 

Ex : 

89 people had a favorable opinion of capital punishment

77 of these had untapped skills  = (77/89)  = 86.5%

But  only 12  had max skills  =  (12/89)  = 13.5%

 

 

cool cool cool

Thanks again, CPhill, for your efforts! I didn't know how to approach this kind of problem, so I needed help to learn about this probability issue. I also posted another math problem similar to this one that you can check out here.
