When I was fifteen months old．I fell on a glass rabbit which cut my eye badly enough to blind it．And as I grew，this sightless eye , in so many ways controlled me that I walked with my face looking at the floor so people would not see the ugly me．
Yet Mama would hold me in her arms and stroke my hair and say，“If you hold your head up high，it will be OK．And people will see your beautiful soul．”She continued this message whenever I wanted to hide．
As a little child，I thought Mama meant，“Be careful or you will fall down or bump into something because you are not looking．”As a teenager, I found that my mama’s words helped me begin to realize that by letting people look at my face，I let them recognize the intelligence and beauty behind my eyes．
In high school I was successful both academically and socially．I was even elected class president，but inside me I still felt like a freak(畸形人)．When things got really bad，I would cry to my mama and she would look at me with loving eyes and say, “Hold your head up high and face the world．Let them see the beauty that is inside．”
When I met the man who became my partner for life，we looked each other straight in the eye，and he told me I was beautiful inside and out．Mama’s love and encouragement were the spark that gave me the confidence to overcome my own doubt．
“Hold your head up high” has been heard many times in my home．Each of my children has felt its invitation．The gift my mama gave me lives on in another generation．

在图中，从“厂”结点出发选择三个车间产品的概率分别为 0.4、0.3、0.3，从各“车间”结点出发选择“正品”或“次品”的概率如图所示。从“厂”结点出发，到达“正品”（或“次品”）结点，可以有多条路径。例如，路径“厂—甲—次品”表示该厂甲车间生产的次品，其概率 P（厂—甲—次品）应等于各段上的概率之积。而该厂总的次品率应等于从“厂”结点到达“次品”结点的所有路径算出的概率之和（全概率公式）。而其中每条路径算出的概率在总概率中所占的比例，就是已知抽取产品结果再推测其来源（路径）的概率（逆概率公式）。根据以上描述，可以算出，该厂的正品率约为 （） 。如果上级抽查取出了一个次品，那么，该次品属于甲车间生产的概率约为 （） 。
