Answer: She apparently was convicted in a jurisdiction that used indeterminate (not determinate) sentencing, allowed a life sentence to be "with the possibility of parole" and sentencing philosophy of "let the punishment fit the criminal (not the crime). " When there is no mandatory minimum number of years to be served in prison, a convicted murderer (of various°) could actually serve relatively few years in prison with the remainder of the sentence served outside of prison (such as in a halfway house or residential treatment center, or in her own home under electronic monitoring) provided the offender does not violate the conditions of release. An offender receiving a sentence of "life imprisonment", for example, could serve the first several years in prison and then be released to a halfway house to continue "serving time" outside of prison (with supervision). The years served "in the community" are still "time served" under the sentence - only the location of serving it has changed.

Answer: To start, this film gets a lot wrong about the judicial system and law (including the whole idea that Libby can freely kill Nick because she's already been convicted of his murder). In the film, they just say she's charged with murder, but never what degree. In Washington State, 2nd degree murder generally carries a sentence of 10-18 years (not including felony-murder). However, Washington State did not offer parole at the time of the film like other states did. To be released, she'd have a hearing in front of the Washington State Clemency and Pardons Board, not a Parole Board. And it's unlikely they'd grant her a release. But in Texas for example, she could possibly get parole after serving at least half her sentence.
