Three dice, each with faces numbered 1 through 6, were tossed onto a game board. If one of the dice turned up 4, what was the sum of the numbers that turned up on all three dice?
(1)The sum of two of the numbers that turned up was 10.
(2)The sum of two of the numbers that turned up was 11.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
注意题目只需要三个骰子的总和，假设三个数为 x y 4
如果4和其中一个数的总和是11，则＝4+7（骰子最多只有6），所以必为x+y=11，所以总和为15
唉又粗心了
