以下是小编搜索整理的有关新gre考试数学排列组合例题分析,Gre改革,减少了词汇量的考察,也相应的提高了逻辑阅读能力和数学的难度,所以考生在答新gre数学试题时,一定要细心认真,把握好时间,最好有做完检查的时间,尽量在新gre数学部分取得高分。发挥好我们gre数学优势的同时,积极应对新gre逻辑阅读考试。
练习题:
1:A, B独立事件,一个发生的概率是0.6 ,一个是0.8,问:两个中发生一个或都发生的概率 ?
解答:
P=P+P+P
=0.6+0.8+0.60.8=0.92
另一个角度,所求概率P=1-P
=1-=0.92
2:一道概率题:就是100以内取两个数是6的整倍数的概率.
解答:100以内的倍数有6,12,18,...96共计16个
所以从中取出两个共有1615种方法,从1-100中取出两个数的方法有99100种,所以P=/=12/505=0.024
3:1-350 inclusive 中,在100-299inclusive之间以3,4,5,6,7,8,9结尾的数的概率.
因为100-299中以3,4,5,6,7,8,9结尾的数各有20个,所以
Key:/350=0.4
4.在1-350中,337-350之间整数占的百分比
虽然新版gre数学部分难度系数有所提高,但相信我们国内考生能够从容应对,以上即是小编搜索整理的有关新gre数学排列组合方面的练习题。希望能广大考生有所帮助。
