On the distant planet Cowabunga , the weights of cows have a
normal distribution with a mean of 357 pounds and a standard
deviation of 48 pounds. The cow transport truck holds 10 cows and
can hold a maximum weight of 3910. If 10 cows are randomly selected
from the very large herd to go on the truck, what is the
probability their total weight will be over the maximum allowed of
3910? (This is the same as asking what...
