Let X the random variable that represent the IQ scores, and for this case we know the distribution for X is given by:
Where 
and 
We want to find this probability
And we can use the z score formula given by:
If we apply this formula to our probability we got this:
And we can find this probability with this difference:
And in order to find these probabilities we can use the normal standard table or excel and we got.
