关于条件概率的问题

night-shift workers :A
female workers :B
favoured he plan :C
60% of all night-shift workers favoured he plan :P(C│A)=0.6
35% of all female workers favoured the plan;P(C│B)=0.35
45% of all enployees are night-shift workers:P(A)=0.45
25% of all employees are women:P(B)=0.25
15% of night-shift workers are women:P(AB)=0.15
60% of all male employees favoured the scheme:P(C│B\)=0.6
both dose not work night-shift and dose not favour :P(A\C\)
p(A\C\)=p(A\)-P(A\C) P(A\)=1-P(A)=0.55
P(AC)=p(A)* P(C│A)=0.6*0.45=0.27
P(C)=P(BC)+P(B\C)=P(B)*P(C│B)+P(B\)*P(C│B\仔蔽碧)=0.25*0.35+0.75*0.6=0.5375
P(A\C)=P(C)-P(AC)=0.5375-0.27=0.2675
p(A\并雹C\)=p(A\)-P(A\C) =0.55-0.2675=0.2825
A\ B\ C\念举 :A B C Opposition events
