Defect 1 present:
Defect 1 not present :
Defect 2 present:
Defect 2 not present :
Defect 1, not defect 2:
Defect 2, not defect 1:
Defect 1, defect 2 :
So then summing those probabilities,

You could have also figured out the probability that neither defect exists,

The complement would be either one defect or both defects exist so,
