This is what i have come up with so far. P(republican) = .45 P(democrat) = .55 P(republican and favors) = .25*.45 P(democrat and favors) = .75 *.55 P(favor) = P(republican AND favors) + P (democrat AND favors) therefore P(democrat given that favors) = P(democrat and favors)/ (Pfavors)

Hm, well this is what I came up with. Still thinking about it. 45*4 republicans and 55*4 democrats, let If 25% of republicans favor an issue means=45 and 75% of democrats favor an issue means = 165 total who favours = 210 P of her to be democrat= 165/210 .785
