Object E is dependent on Objects A and B.

P(A works) = 0.90

P(A fails) = 0.10

P(B works) = 0.90

P(B fails) = 0.10

If Object A works, then Probability of Object E working is 0.6

If Object A fails, then Probability of Object E working is 0.2

If Object B works, then Probability of Object E working is 0.6

If Object B fails, then Probability of Object E working is 0.2
