The primary purpose of the preliminary hearing s to hear the formal information or indictment and to allow the defendant to enter a plea?

The primary purpose of a preliminary hearing is to determine whether there is enough evidence to proceed with a trial, rather than to hear formal information or an indictment. During this hearing, the judge assesses whether probable cause exists to believe that a crime was committed and that the defendant committed it. It is also an opportunity for the defense to challenge the prosecution's evidence. The defendant typically enters a plea during arraignment, which occurs after the preliminary hearing.
