Work: Calculate the value of equation 40%*70%*70%+(1-40%)*70%*70%+40%*2*70%*(1-70%) .
Question type: Mathematical calculation
Solution:
40%*70%*70%+(1-40%)*70%*70%+40%*2*70%*(1-70%)
=40%*70%*70%+0.6*70%*70%+40%*2*70%*(1-70%)
=40%*70%*70%+0.6*70%*70%+40%*2*70%*0.3
=0.4*70%*70%+0.6*70%*70%+40%*2*70%*0.3
=0.4*0.7*70%+0.6*70%*70%+40%*2*70%*0.3
=0.4*0.7*0.7+0.6*70%*70%+40%*2*70%*0.3
=0.4*0.7*0.7+0.6*0.7*70%+40%*2*70%*0.3
=0.4*0.7*0.7+0.6*0.7*0.7+40%*2*70%*0.3
=0.4*0.7*0.7+0.6*0.7*0.7+0.4*2*70%*0.3
=0.4*0.7*0.7+0.6*0.7*0.7+0.4*2*0.7*0.3
=0.28*0.7+0.6*0.7*0.7+0.4*2*0.7*0.3
=0.196+0.6*0.7*0.7+0.4*2*0.7*0.3
=0.196+0.42*0.7+0.4*2*0.7*0.3
=0.196+0.294+0.4*2*0.7*0.3
=0.196+0.294+0.8*0.7*0.3
=0.196+0.294+0.56*0.3
=0.196+0.294+0.168
=0.49+0.168
=0.658
Answer:40%*70%*70%+(1-40%)*70%*70%+40%*2*70%*(1-70%)=0.658
