问题 单项选择题

风险的成本估算完成后,可以针对风险表中的每个风险计算其风险曝光度。某软件小组计划项目中采用50个可复用的构件,每个构件平均是100LOC,本地每个LOC的成本是13元人民币。下面是该小组定义的一个项目风险:
1.风险识别:预定要复用的软件构件中只有50%将被集成到应用中,剩余功能必须定制开发;
2.风险概率:60%;
该项目风险的风险曝光度是 (15)

A.32500

B.65000

C.1500

D.19500

答案

参考答案:D

解析:[分析] 风险曝光度(riskexposure)的计算公式如下:
风险曝光度=错误出现率(风险出现率)×错误造成损失(风险损失)
在本题中,风险概率为60%,风险损失为所有构件价格的50%,因此,其风险曝光度为:
50×100×13×50%×60%=19500

American schools do not have separate classes for boys and girls. If boys want to cook or to sew, they can learn these things in classes that are no longer just for girls. If girls want to repair cars, they can now learn this in school. Most students like to have boys and girls on the same baseball team.

Many boys and girls dress alike in school. They were blue jeans and sport shirts. Some have long hair and some have short hair. Sometimes a boy has longer hair than a girl.

Even the language is different. Students learn to say fire fighter instead of fireman, police officer instead of policeman, and letter carrier instead of mailman. A person does not need to be a man to fight a fire or to deliver the mail.

Most people think that these changes are good. They give all people an equal chance to be happy and to do what they want to do with their lives. Fathers like to tell their sons that they can grow up to be president. Today, mothers can tell the same things to there daughters.
