title: How to change the z value to the one from the table (Z-Table from Normal Distribution) in C++?
body: <p>i have task to make a program using C++ to calculate a probability using a normal distribution. If i already found the Z value, how to change it to become the one from the Z table? Like -0.55, in the z-table is 0.29116. And 0.85 in the table is 0.80234. </p>
  
  <p>Because what i know array is only know what column and row to display.
  Thanks.</p>
