Your store is interested in learning more about customers’ purchasing
patterns and how they relate to the frequency of store visits. The probability
that a customer’s visit will result in a purchase is 0.35. The probability that
a customer has been to the store within the past month is 0.20. Of those who
did not buy anything, 12% had been there within the past month.
a. Find the probability of making a purchase given that the customer had been to the store within the past
month.
b. What percent of customers are frequent shoppers, defined as making a purchase and having been to thestore within the past month?
答案分别是:0.61 & 0.122
第一个答案是:0.61额。。
追答题目的意义太拗口。
1.顾客进入商店后消费的概率是0.35。
2.顾客曾经在一个月内来过的概率是0.20.
3.没有消费的顾客中,12%的人一个月内没有来过。
问:a.一个月内来过商店的顾客做出消费的概率。
b.常客,即一个月内来过并消费的顾客,的比例。
这两问的意义哪里不同,我已经迷糊了。
所以我拿上来问,老师讲得模模糊糊的 或者是我就没听懂他说的
追答能不能把0.61这个数字凑出来,反推回去看看
