Calculate cumulative probabilities for normal distributions. Find P (X ≤ x), P (a ≤ X ≤ b), or P (X < a or X > b) for any mean and standard deviation. The Normal Cumulative Distribution Function (CDF) …

The normal distribution calculator works just like the TI 83/TI 84 calculator normalCDF function. It takes 4 inputs: lower bound, upper bound, mean, and standard deviation.

If a random variable is normally distributed, you can use the normalcdf command to find the probability that the variable will fall into a certain interval that you supply.
