Pa=0.15+0.85(Pc)
Pb=0.15+0.85(0.5Pa)
Pc=0.15+0.85(0.5Pa+Pb)

sol:

1)Pb=0.15+0.85*0.5(0.15+0.85Pc)=0.15+0.06375+0.36125Pc=0.21375+0.36125Pc

2)Pc=0.15+0.85[0.5(0.15+0.85Pc)+ 0.21375+0.36125Pc]

       =0.15+0.85[0.075+0.425Pc+0.21375+0.36125Pc]

       =0.15+0.85[0.28875+0.78625Pc]=0.15+0.2454375+0.6683125Pc

       =0.3954375+0.6683125Pc

3)0.3316875Pc=0.3954375 

=>Pc=1.19219898

4)帶入1式

   Pb=0.21375+0.36125*(1.19219898)=0.64443188

5)Pa=0.15+0.85*1.19219898=1.16336913
