EDEXCEL S1 question

Hi,
I was practising past papers today and I was wondering how to find the most accurate value of the area under the curve of a normal distribution given a z score. I have a Casio fx-83GT plus so it doesn't integrate. Does anyone know how?

You are expected to use the tables. There are two; one that covers loads of z values and a second, smaller table that had more exact z values for probabilities like 0.01 and 0.001 and 0.005 etc.
