Answer by jojo14344(1513) (Show Source): You can put this solution on YOUR website!
Out of 289 reviewed, you're % of error is,
=4.15%
Or,
=95.85% are right.
Of the remaining you didn't review (1214-289) you assumed they're right.
The more glucose you review, the lesser your percentage of error if it remains at 12 errors.
Thank you,
Jojo
