Question

This is uuurgeeent. The diameters produced by a machine are normally distributed with a mean of 10cm and a standard deviation of 0.1cm. Find the probability of the machine producing a disk with a diameter less than 10.5cm

Answer 1

I tried using standardized normal variable but for z=5 my strd. normal variable table does not give anything. How to solve this?

Answer 2

or is the standard deviation just too small for the table that I'm using? my calculations worked fine when i made strd deviation 1
