We should ask the injured person if he is OK, and see if he is breathing. What’s more, we should check for cuts and wounds.

If necessary, take the injured person to the hospital as soon as possible.Do remember: when giving first aid, please be sure to place the person in a recovery position.

4.寫出下列隨機變量可能取的值,并說明隨機變量所取的值表示的隨機試驗的結(jié)果.(1)一個袋中裝有8個紅球,3個白球,從中任取5個球,其中所含白球的個數(shù)為X.(2)一個袋中有5個同樣大小的黑球,編號為1,2,3,4,5,從中任取3個球,取出的球的最大號碼記為X.(3). 在本例(1)條件下,規(guī)定取出一個紅球贏2元,而每取出一個白球輸1元,以ξ表示贏得的錢數(shù),結(jié)果如何?[解] (1)X可取0,1,2,3.X=0表示取5個球全是紅球;X=1表示取1個白球,4個紅球;X=2表示取2個白球,3個紅球;X=3表示取3個白球,2個紅球.(2)X可取3,4,5.X=3表示取出的球編號為1,2,3;X=4表示取出的球編號為1,2,4;1,3,4或2,3,4.X=5表示取出的球編號為1,2,5;1,3,5;1,4,5;2,3,5;2,4,5或3,4,5.(3) ξ=10表示取5個球全是紅球;ξ=7表示取1個白球,4個紅球;ξ=4表示取2個白球,3個紅球;ξ=1表示取3個白球,2個紅球.
一、 問題導學前面兩節(jié)所討論的變量,如人的身高、樹的胸徑、樹的高度、短跑100m世界紀錄和創(chuàng)紀錄的時間等,都是數(shù)值變量,數(shù)值變量的取值為實數(shù).其大小和運算都有實際含義.在現(xiàn)實生活中,人們經(jīng)常需要回答一定范圍內(nèi)的兩種現(xiàn)象或性質(zhì)之間是否存在關(guān)聯(lián)性或相互影響的問題.例如,就讀不同學校是否對學生的成績有影響,不同班級學生用于體育鍛煉的時間是否有差別,吸煙是否會增加患肺癌的風險,等等,本節(jié)將要學習的獨立性檢驗方法為我們提供了解決這類問題的方案。在討論上述問題時,為了表述方便,我們經(jīng)常會使用一種特殊的隨機變量,以區(qū)別不同的現(xiàn)象或性質(zhì),這類隨機變量稱為分類變量.分類變量的取值可以用實數(shù)表示,例如,學生所在的班級可以用1,2,3等表示,男性、女性可以用1,0表示,等等.在很多時候,這些數(shù)值只作為編號使用,并沒有通常的大小和運算意義,本節(jié)我們主要討論取值于{0,1}的分類變量的關(guān)聯(lián)性問題.
溫故知新 1.離散型隨機變量的定義可能取值為有限個或可以一一列舉的隨機變量,我們稱為離散型隨機變量.通常用大寫英文字母表示隨機變量,例如X,Y,Z;用小寫英文字母表示隨機變量的取值,例如x,y,z.隨機變量的特點: 試驗之前可以判斷其可能出現(xiàn)的所有值,在試驗之前不可能確定取何值;可以用數(shù)字表示2、隨機變量的分類①離散型隨機變量:X的取值可一、一列出;②連續(xù)型隨機變量:X可以取某個區(qū)間內(nèi)的一切值隨機變量將隨機事件的結(jié)果數(shù)量化.3、古典概型:①試驗中所有可能出現(xiàn)的基本事件只有有限個;②每個基本事件出現(xiàn)的可能性相等。二、探究新知探究1.拋擲一枚骰子,所得的點數(shù)X有哪些值?取每個值的概率是多少? 因為X取值范圍是{1,2,3,4,5,6}而且"P(X=m)"=1/6,m=1,2,3,4,5,6.因此X分布列如下表所示
