解题方法
6 . 2023年高考分数公布后,经过相关部门的计算,本次高考总分不低于680的同学可以获得高校
的“强基计划”入围资格.经统计甲班和乙班分别有3名和4名学生获得高校
的“强基计划”入围资格,而且甲班和乙班高考分数高于690分的学生分别有1名和2名.高校
的“强基计划”校考分为两轮.第一轮为笔试,所有入围同学都要参加,考试科目为数学和物理,每科的笔试成绩从高到低依次有
,
,
三个等级,两科中至少有一科得到
,且两科均不低于
,才能进入第二轮.已知入围的同学参加第一轮笔试时,总分高于690分的同学在每科笔试中取得
,
,
的概率分别为
,
,
;总分不高于690分的同学在每科笔试中取得
,
,
的概率分别为
,
,
;进入第二轮的同学,若两科笔试成绩均为
,则免面试,并被高校
提前录取;若两科笔试成绩只有一个
,则要参加面试,总分高于690分的同学面试“通过”的概率为
,总分不高于690分的同学面试“通过”的概率为
,面试“通过”的同学也将被高校
提前录取.若甲、乙两个班本次高考总分不低于680的同学都报考了高校
的“强基计划”.
(1)分别求出总分高于690分的某位学生进入第二轮的概率以及该生被高校
提前录取的概率;
(2)从甲、乙两班随机抽取一个班,再从该班获得高效
的“强基计划”入围资格的学生中随机抽取2位学生,求这两位同学都通过“强基计划”被高校
提前录取的概率.
