# How to Write Probability Notations

When finding probabilities for a normal distribution (less than, greater than, or in between), you need to be able to write probability notations. Practice these skills by writing probability notations for the following problems.

## Sample questions

1. Write the probability notation for the area shaded in this Z-distribution.

Looking at the graph, you see that the shaded area represents the probability of all z-values of 2 or less. The probability notation for this is

2. Write the probability notation for the area shaded in this Z-distribution.
