Since no specific method was stipulated the combinations of three different regions from the 10 possible regions that would result inexactly 50 points is Zero.
<h3>Possible Scores</h3>
The possible scores are given below:
10 10 10, 10 10 5, 10 5 5, 5 5 5, 10 10 1, 10 1 1, 10 5 1, 5 5 1, 5 1 1 and 1 1 1.
The sum of each group of possible scores are:
3, 7, 11, 16, 12, 21, 15, 20, 25, 30
Examples of rudimentary addition:
1. 3+7+30 =40
2. 7+11+30=48
3. 11 + 16 + 30= 57
4. 16+12+30 =58
5. 12+21+30=63 etc
Again, using a rudimentary count, we can prove that no three categories all summed up, will add up to exactly 50 points.
