Can someone show me how to do this onexcel?
Question involves cell phone users.
Mean monthly data usage = 5.8 GB/month
StDev monthly data usage = 2.5 GB/month
"Heavy users" are those that use >= 9 GB/month
a.) What is the probability a "heavy user" uses more than 10GB/month?
b.) Two users are selected at random. What is the probability atleast one of them is a heavy user?
c.) Five users are selected at random. What is the probabilitythat at least one of them is a heavy user?
Again, I am looking for the EXCEL formula to solve these. THANKYOU!!!!
