An investment,each quarter has 16% probability to lose money
each quarter follows i.i.d. normal distribution
Q: what is the probability of losing money by the end of the year?
面试官提示把16%跟normal分布的mean和deviation联系起来
不过我连题目也不甚明白
比如要是Q1 lose money, 然后Q2,Q3,Q4 win money
那么这一整年到底算win还是lose呢?
哪位大虾给解释下
谢谢!
