之前跟一位同學要了一份機經來做~ 所以忘記是多久之前的機經了~ 題目是: 1) This morning Pat went to the supermarket with a red bag and a green. If he bought 10 carrots and 6 radishes, in how many ways could he distribute these vegetables so that no bag would be empty? (A)120 (B)75 (C)60 (D)54 (E)45 他給的答案是(B) 想請教一下有人可以跟我講說這題要怎麼解嗎?? 2) Orange juice of normal strength is prepared by adding three-6 ounce cans of water to the concents of a 6-ounce can of orange juice concentrate. If 1 ounce of the can of concentrate was already used for some other purpose, how many 6-ounce cans of water should be added to the remainder of the concentrate to prepare juice of normal strength? 給的答案是 2.5 這題也是解好久都解不出來~ 以上這兩題希望會的人教教我!!! 謝謝~~~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.136.84.147
