Combining,

nina: -1,-2, Teri: -3,-6=> Teri wins.
hey,
I think both the statements are sufficient as
statement 1 says nina's first die value is already greater than teri's both values.
and simililarly 2nd statement aswell..
I need help in getting to insufficient conclusion.
thanks in advance
The given example is a little messed up. In case
nina: 4,6 Teri: 1,2 => then Nina's score is -10 and Teri's score is -3 so Teri wins, not Nina.
There are two different things here: Sum of the die and overall score
Overall score is negative of sum of the die.
If Nina's first die value is greater than Teri's sum of the die, Nina's sum of the die could be greater than or less than Teri's sum of the die depending on Nina's second die value (since the die value can be negative too). Thereafter, the overall score of Nina could be less than or greater than Teri's.
Using both statements together, we can find cases in which Nina wins and other cases in which Teri wins.
Say, Teri's die values are -3 and -3. Sum of both dice is -6 (and overall score is 6).
Say, Nina's first die value is -1 and second die value is -1 (Nina's each die value is more than the sum of Teri's both dice) . Sum of both dice is -2 and overall score is 2.
Teri wins
Say, Teri's die values are -4 and -1. Sum of both dice is -5 (and overall score is 5).
Say, Nina's first die value is -4 and second die value is -4 (Nina's each die value is more than the sum of Teri's both dice) . Sum of both dice is -8 and overall score is 8.
Nina wins
