You can put this solution on YOUR website!
P(Good)P(Good)=%280.992%29%280.992%29=0.984064
P(Good)P(Bad)=%280.992%29%280.008%29=0.007936
P(Bad)P(Good)=%280.008%29%280.992%29=0.007936
P(Bad)P(Bad)=%280.008%29%280.008%29=0.000064
P(one or both bad)=0.007936%2B0.007936%2B0.000064=0.015936
You could have also done,
P(one or both bad)=1-P(both good)=1-0.984064=0.015936
