if you want to go the long way you can go one by one to get the answer (shown here) 1 + 5.9= 6.9 divided by 2 = 3.45 (not a win)
2+ 5.9= 7.9 div. by 2 = 3.95 (not a win)
3+ 5.9= 8.9 div. by 2 = 4.45
4+ 5.9= 9.9 div. by 2 = 4.95
5+ 5.9= 10.9 div. by 2 = 5.45
6+ 5.9= 11.9 div. by 2 = 5.95 Win the lowest score Winona can get is a 6 in order to get the winning score.
