A defendant is found guilty of armed robbery and is sentenced to 5–10 years in prison. This is an example of an indeterminate sentence.
Explanation:
When the punishment sentenced does not specifically define an exact period of punishment, it is considered as indeterminate punishment.
If the sentence says that the punishment would last for 5 to 10 years, it means that the criminal should be kept imprisoned for at least 5 years but not more than 10 years.
