133 product evaluation

by ern5231 » Tue Oct 06, 2009 2:39 pm
Evaluation of four features of a product. Evaluation rated the features as excellent/good/qualified/unqualified. Did atleast 12 people rate excellent or good on the same two features?

1) exactly 10 people say excellent on 2 features
2) exactly 12 people say good on 3 features
