The `probability` function calculates the probability that a value drawn from a numeric field will fall within specific range. The `probability` function takes four parameters:
1. the numeric field to compute the probability from
2. the numeric start range
3. the numeric end range
4. the sample size
## Sample syntax
```sql wrap theme={"dark"}
select probability(sepal_length_d, 5.1, 7.7, 150) as prob
from iris
```
## Result set
The result set for the `probability` function contains a single record with the calculated probability. The `probability` function returns the probability calculation.
Sample result set in Apache Zeppelin
