Problem 1: Assume the number of downloads per day of a popluar APP A follows a normally distribution with a mean of 2800 and standard devation of 860. Answer the following questions: 1) What is the probability there are 2000 or fewer downloads in a day? 2) What is the probability ther are between 1500 and 2500 downloads in a day? 3) What is the probability there ar more than 3000 downloads in a day? 4) Assume the company providing the downloading service has designed its servers so there is probability 0.01 that the number of downloads in a day exceeds the serviers' capacity and more servers have to be brought online. How many downloads per day are the servers designed to handle?
