【沃顿商学院《运营管理概论》题目求教 -不良品被转移到发运部的概率有多大】有一条50道工序的生产线，每道工序产生质量缺陷的可能性是1%，其中任何一道工序产生缺陷都会导致最终产品的不良；生产线尾部有2个独立工作的质检员，每人捉到不良品的可能性是90%，抓到就报废，认为合格就转到发运部。
问题1：该生产线产生不良品的概率是多大？（不管是否有不良品是否被抓到没有）
- 这道题答案很简单，0.394994
问题2：不良品被转移到发运部的概率有多大？- 这道题，我提交的答案是0.061286，但结果是错的
Consider an assembly
line with 50 steps that are carried out sequentially. Each of the 50 steps has
a defect probability of 1%. The final product produced on the assembly line is
defective if any one of the 50 steps made a defect.
At the end of the
assembly line there are two operators independently inspecting the product.
Each of them is recognizing a defective product with a 90% probability.
Assuming that the product is not defective, it is moved to the shipping
department. Otherwise, the product is scrapped.
50SAL1. What is the probability that a defective
product is produced (independent of the defect being found or not)?
50SAL2. What is the probability that a defective product is moved to the
shipping department?
