It seems like not having the value in your table would be a problem, but it's a very small one $-$ since your answer for $P(01$ and $Z< -1$), the integral will be bounded below by the midpoint rule and above by the trapezoidal rule, which usefully bounds where the answer can lieīut, really, just using the limits provided by 3 and $\infty$ is plenty, I imagine.
Your question should therefore be modified to ask "*How do I deal with the fact that my table doesn't go as high as my $Z$ value?*" Finding Areas Under a Normal Curve Using the Table Draw a sketch of the normal curve and shade the desired area. Standard scores are most commonly called z-scores.
Your problem appears to be that your table doesn't go further. Z table or the Z-score table also called the standard normal table is a mathematical table used to find the probability that the z-score value is below, above, or between the values on the standard normal distribution. In case you get a positive z score, then you know that the value is above the mean. It simply shows the position of the raw score in terms of the distance of this score from the mean when you measure it in standard deviation units. The standard normal ranges from $-\infty$ to $\infty$. A z score can be placed on a normal distribution curve.
