17.解：從高三年級抽取的學(xué)生人數(shù)為185(7560)50

而抽取的比例為501100020，高中部共有的學(xué)生為185120370018.解：在[60,70]的汽車的頻率為0.04100.4，在[60,70]的汽車有201*.48019.解：（1）記甲被選中為事件A，則P(A)3612

（2）記丁被選中為事件B，則P(B)1P(B)1121220.解：（1）有放回地抽取3次，按抽取順序(x,y,z)記錄結(jié)果，則x,y,z都有10種可能，所以

試驗(yàn)結(jié)果有101010103種；設(shè)事件A為“連續(xù)3次都取正品”，則包含的基本事件共有

88883種，因此，P(A)831030.512（2）可以看作不放回抽樣3次，順序不同，基本事

件不同，按抽取順序記錄(x,y,z)，則x有10種可能，y有9種可能，z有8種可能，所以試驗(yàn)的所有結(jié)果為1098720種．設(shè)事件B為“3件都是正品”，則事件B包含的基本事件總數(shù)為876,所以P(B)33672021.解：記男生為a,b,c,d,女生為1，2，基本事件為：

（a,b,c）(a,b,d)(a,b,1)(a,b,2)(a,c,d)（a,c,1）(a,c,2)(a,d,1)（a,d,2）(a,1,2)(b,c,d)(b,c,1)(b,c,2)（b,d,1）(b,d,2)(b,1,2)(c,d,1)(c,d,2)(c,1,2)(d,1,2)共20個(gè)①所選3人都是男生的事件數(shù)為4,P4201*②所選3人恰有1女生的事件數(shù)為12,P122035③所選3人恰有2女生的事件數(shù)為4,P41314205所選3人中至少有1名女生的概率為55522.解：（1）基本事件總數(shù)為4312，設(shè)方程有實(shí)根為事件A則A包含：

4a24b20a2b2ab又a0,b0ab

當(dāng)a4時(shí)，b1,2,3a2時(shí)，b1,2當(dāng)a3時(shí)，b1,2,3，當(dāng)

當(dāng)當(dāng)a1時(shí)，b1共計(jì)9種，p(A)912（2）設(shè)方程有實(shí)根為事件B則(a,b)|4a1,1b3

B(a,b)|4a1,1b3,ab在坐標(biāo)系中畫出，B表示的區(qū)域（本處略）
