thanks for that samthedog, that is a help. I do have one of those 'flashy graphics' calculators. How would i work this out on my calculator if i don't have access to a z table ?

try this link: http://en.wikipedia.org/wiki/Normal_distribution and scroll down to "Probability Density Function"...
This might help...

This number for z must be looked up in a normal distribution table. However, most tables give answers for the larger section of the distribution so you will have to subtract this answer from !. Alternatively , you could use a flashy graphics calculator.
