The minimum force required to break a particular type of cable is normally distributed with mean 12,432 and standard deviation 25. A random sample of 400 cables of this type is selected.
Calculate the probability that at least 349 of the selected cables will not break under a force of 12,400..

PS: central limit theorem is of no use..

What have you covered in class that looks exactly like this? Side note, that is a pretty small standard deviation.
