[計量] 請問CAT 12問題
1.The maximum number of non-overlapping regions into which 3 lines can divide
the interior of a circle
Ans : 7
我是土法鍊罁用畫的 不過有什麼算法會更好嗎? 如果題目問更多線我就掛掉了
2. Col A : The probability of the point that is not inside the circle O
if a point is chosen at random from inside the triangle
Col B : 1/2
Ans : (B)
3. r < t + 5
Col A : r
Col B : t
Ans : (D)
有什麼情況會 t > r 呢?我數字代入都r比較大
4. A bowl contains red, green and white balls. The probability of choosing a
red ball is 1/3. There are 5 more green balls than red ones, and there are
12 white balls total. What is the odds against choosing a white ball?
Ans : 13/4
請問這題跟它的上一題(問the probability of choosing a white ball)有什麼差別?
不好意思 麻煩各位幫忙了
謝謝
