以下是引用cournot在2006-6-2 10:49:00的发言:如果是这样的话,好像B是对的,因为 category 1: Foreign domestic submit 2 8 accept 1 4 原文假设1,意思是每组出现名额N一定,美国片和外国片一起抢N个名额。 所以这里不是1,4!应该是N1,rate:N1/(2+8) category 2: Foreign domestic submit 3 6 accept 1 3 所以这里不是1,3!应该是N2,rate:N1/(3+6) 每个category接受比列一样1/2=4/8,1/3=3/6; 总的接受比列:2/5<7/14,B 正确 Significantly more domestic films than foreign films were submitted to the festival. 这样解释可以么? 所以,外国片都在出线率低的组中。 做错是这句话会错意了Within each category, the rate of acceptance for domestic films was the same as that for foreign films. |
