Using the above * normal distribution curve calculator* , we are able to compute probabilities of the form \(\Pr(a \le X \le b)\), along with its respective * normal distribution graphs* . This not exactly a normal probability density calculator, but it is a normal distribution (cumulative) calculator. Change the parameters for a and b to graph normal distribution based on your calculation needs. If you need to compute \(\Pr(3 \le X \le 4)\), you will type “3” and “4” in the corresponding boxes of the script.
