Q1. ┌───┬───┐ │ Teams│Scores│ ├───┼───┤ In a contest, 5 judges evaluate 8 teams with the │ A │ 14 │ scores from 0 to 10, and the table above list ├───┼───┤ (就是左邊那個圖表) the scores of 8 different │ B │ 17 │ groups. Based on the scores, how many of the teams ├───┼───┤ must have at least 7 scores from one judge? │ C │ 25 │ ├───┼───┤ (A)4 (B)5 (C)6 (D)7 (E)8 │ D │ 29 │ ├───┼───┤ Ans.(A) │ E │ 31 │ ├───┼───┤ │ F │ 35 │ ├───┼───┤ │ G │ 44 │ ├───┼───┤ │ H │ 49 │ └───┴───┘ Q2. In a certain class a professor awards his students grades A, B, C, D, and F. If at least one of the grades has 6 or more students, what is the least total number of students in the class? (A)30 (B)27 (C)26 (D)25 (E)22 Ans.(C) 這題我的想法是，只要有一個grade有6個學生那其他grade低於6，這樣(E)不是更好? 想了很久還是想不通，希望有人能夠幫忙解答，謝謝^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.225.15.152
