证明: (1)A=A(B∪ B )=AB∪A B =AB∪ A B=(A∪ A )B=B。 (2)因为 A B A B =Φ,所以 P(A B ∪ A B)= P(A B )+ P( A B)- P (A B A B)= P(A B )+ P( A B)=P(A)-P(AB)+P(B)-P(AB) =P(A)+P(B)-2P(AB) 。 5、10 片药片中有 5 片是安慰剂。 (1)从中任意抽取 5 片,求其中至少有 2 片是安慰剂的概率。 (2) 从中每次取一片, 作不放回抽样, 求前 3 次都取到安慰剂的概率。 解:
5 1 5 (1)p=1- C55 / C10 - C5 。 C54 / C10 3 (2)p= A53 / A10 。

6、在房间里有 10 个人,分别佩戴从 1 号到 10 号的纪念章,任选 3 人记录其纪念章的号码。 (1)求最小号码为 5 的概率。 (2)求最大号码为 5 的概率。 解:
3 (1)从 10 人中任选 3 人的选法有 C10 种。要求最小号码为 5,即有一

个人的号码是 5, 其他两人的号码都在 6 到 10 之间。 故共有 C52 种不同
3 的选法。故最小号码为 5 的概率 p= C52 / C10 。

解: (1)设 A 表示事件“从甲袋中取到的是红球” ,B 表示事件“从乙袋中取 到的是白球” 。则 P(B)=P(AB)+P( A B)=+P( A B C)= P(A) P(B|A)+P( A )P(B| A )=m/(m+n)×N/(M+N+1)+ n/(m+n) ×(N+1)/(M+N+1)。 (2)设 A 表示事件“从第一个盒子中取到 0 个红球” ,B 表示事件“从第 一个盒子中取到 1 个红球” , C 表示事件“从第一个盒子中取到 2 个红球” , D 表示事件“从第二个盒子中取到白球” 。则 P(D)=P(AD)+P(BD) +P(CD)=P(A)P(D|A)+ P(B)P(D|B)+ P(C)P(D|C)
1 1 1 1 1 1 1 1 = C 42 / C92 × C7 / C11 + C4 / C92 × C6 / C11 + C52 / C92 × C5 / C11 。 C5

20、某种产品的商标是“MAXAM” ,其中有 2 个字母脱落,有人捡起 随意放回,求放回后仍“MAXAM”的概率。 解: 设 A1,A2,A3,A4,A5 分别为事件“脱落 M、M” , “脱落 A、A” , “脱 落 M、A” , “脱落 M、X, ” “脱落 A、X, ” 。D 为事件“放回后仍为 MAXAM。 ”
1 1 1 因为 P(A1)= P (A2)= C 22 / C52 ,P(A3)= C 2 / C52 ,P(A4)= C11 C 2 / C52 , C2 1 P(A5)= C11 C 2 / C52 ,P(D|A1)= P(D|A2)=1, P(D|A3)= P(D|A4)

= P(D|A5)=1/2,所以 P(D)= ? P( D | Ak ) P( Ak ) 。

女人数相等的人群中随机地挑选一人, 恰好是色盲患者, 问此人是男性 的概率是多少? 解: 设 A 表示事件“选出的是男性” ,H 表示事件“选出的人是色盲患者” 。 则已知条件 P(A)=1/2,P( A )=1/2,P(H|A)=0.05,P(H| A ) =0.0025。由贝叶期公式可得 P(A|H)=P(H|A)P(A)/[P(H|A) P(A)+ P(H| A )P( A ) ] 。 22、一学生接连参加同一课程的两次考试。第一次及格的概率为 p, 若第一次及格则第二次及格的概率也为 p; 若第一次不及格则第二次及 格的概率为 p/2。 (1) 若至少有一次及格则他能取得某种资格,求他取得该资格的概 率。 (2)若已知他第二次已经及格,求他第一次及格的概率。 解: 设事件 A 表示“第 1 次考试及格” ,事件 B 表示“第 2 次考试及格” , 事件 C 表示“他能取得某种资格” 。 由已知条件可知, P (A) =p, P (B|A) =p,P(B| A )=p/2。 (1)因为 C=A∪ A B,所以 P(C)=P(A)+P( A B)=P(A)+P ( A )P(B| A )=p+(1-p)p/2。
