My question involves criminal law for the state of: PA

My daughter was arrested in PA for shoplifting at a Wal Mart. She was caught pushing out 2 shopping carts full of merchandise out the front door. When LP and the State Police caught her she pepper-sprayed them both. (You read that right)
She is charged with:
F2 18 § 3701 §§A1IV Robbery-Inflict Threat Imm Bod Inj
M1 18 § 2701 §§A1 Simple Assault
M1 18 § 3929 §§A1 Retail Theft-Take Mdse
Her Formal arraignment is coming up. She also has an unrelated DUI charge that she plead guilty to and was just accepted into ARD
Her plan is to plead out and hope for probation. She is one of those people who thinks she's smarter than everyone else.
She won't stop stealing or using. This is he first time she was caught shoplifting, but she has been arrested before...Domestic Violence.

2 questions:
What are the chances that ANYONE would accept a plea deal in this case?
How much time could she be looking at...if any?
