P(M)=.68
P(W)=.32
P(C\M)=42/68
P(C\W)=25/32
P(U|C*M)=1200/4200
P(U|C*W)=1400/2500

P(man with unpaid bal) = P(M*u|c)= P(u|M*c)P(c|m)P(m)/ P(u|M*c)P(c|m)P(m)+ P(u|w*c)P(c|w)P(w) = .12/.12+.14 (everything cancels out!)
Fill in the blanks, AND SUBTRACT FROM 1.. you'll get 0.54... not 0.56 but close enough i guess :P
did anyone do this in any other way?
