Answer:
True.
Step-by-step explanation:
Plea bargaining is the legal term used to define an agreement between the prosecutor and the defendant in which the defendant consent to accept all or some of the charges against him in return of concession by the prosecutor.
When the defendant plea bargaining, the prosecutor agrees to waive some of the charges against the person. in a plea bargain, though some charges are waived of the defendant he also looses three rights in the fifth and sixth amendment namely right to a jury, right to confront witnesses, and right against self-incrimination.
So, the answer is true that plea bargain waives three rights protected by the fifth and sixth amendment.
