The normal distribution is the proper term for a probability bell curve. In a normal distribution, the mean is zero and the standard deviation is 1. It has zero skew and a kurtosis of 3.

The full normal distribution table, with precision up to 5 decimal point for probability values (including those for negative values), can be found here. Let’s see some real-life examples.
