10 . 某高中学校有室内、室外两个运动场.假设同学们可以任意选择其中一个运动场锻炼,也可选择不锻炼,一天最多锻炼一次,一次只能选择一个运动场.若同学们每次锻炼选择去室内、室外运动场的概率均为0.5,每次选择相互独立.设
同学三天内去运动场锻炼的次数为
,已知
的分布列如下:(其中
)
(1)记事件
表示
同学三天内去运动场锻炼
次
;事件
表示
同学在这三天内去室内运动场锻炼的次数大于去室外运动场锻炼的次数.当
时,试根据全概率公式求
的值;
(2)是否存在实数
,使得
?若存在,求
的值;若不存在,请说明理由;
(3)记
表示事件“室外运动场举办集体锻炼活动”,
表示事件“王同学去室外运动场锻炼”,
.已知
同学在室外运动场举办集体锻炼活动的情况下去室外运动场锻炼的概率,比不举办集体锻炼活动的情况下去室外运动场锻炼的概率大,试比较
与
的大小,并证明之.
