Welcome to our interactive Normal Distribution Calculator! This tool is designed to help you quickly and easily calculate probabilities associated with the normal distribution, a fundamental concept in statistics.

How to Use:

1. Enter the Mean (μ) and Standard Deviation (σ) of your normal distribution.
2. Choose a Calculation Type:
   • Less Than: Calculate the probability P(X<X1).
   • Greater Than: Calculate the probability P(X>X1).
   • In Between: Calculate the probability P(X1<X<X2).
3. Input the Value(s) for X1 and, if needed, X2.
4. Click the corresponding button to perform the calculation.
