Explanation / Answer

A) P(republican feeling disgusted) = P(Repubulican and disgusted) / P(republican)

= 220/(220+260+20)

= 0.44

B) P(someone feeling good is a 3rd party) = P(feeling good and third party)/ P(feeling good)

= 10/(260+150+10)

= 0.0238

C) P(democratic and neutral) = 5/1000 = 0.005
