【推荐2】第13届女排世界杯于2019年9月14日在日本举行,共有12支参赛队伍,本次比赛启用了新的排球用球,MIKSA-V200W,已知这种球的质量指标ξ(单位:g)服从正态分布N(270,52).比赛赛制采取单循环方式,即每支球队进行11场比赛(采取5局3胜制),最后靠积分取得最后冠军,积分规则如下:比赛中以3:0或3:1取胜的球队积3分,负队积0分;而在比赛中以3:2取胜的球队积2分,负队积1分.已知第10轮中国队对抗塞尔维亚队,设每局比赛中国队取胜的概率为![](https://staticzujuan.xkw.com/quesimg/Upload/formula/44fed1be8b7e50f18cb90077d9fce8e4.png)
(1)若比赛准备了1000个排球,请估计质量指标在(260,265]内的排球个数(计算结果取整数).
(2)第10轮比赛中,记中国队3:1取胜的概率为
