What could happen to somebody in court if you have three probation violations and their felony and you have one felony failure to appear

There are many variables in what will actually be the result of such a situation - like the persons prior criminal record, the facts of the cases with the felonies, the reasons the person is alleged to have violated probation, etc. But of course, given that the cases are felonies and there are several of them, the result could be a prison sentence of a length decided by the judge. Also, a person might be eligible for 'community corrections' sentence (sentence to prison BUT placement in a halfway house).
