Yup, you can choose what to do you have free will.
We also respond to incentives, rewards etc.. both positive and negative - how you respond is up to you to a large extent.
Questions of determinism etc.. seem a bit misplaced here - my prior at the moment is that the universe isn't deterministic but supposing it were I don't think that matters to you as an individual human*. Even if everything could be known in advance by some observer outside our universe it doesn't change that from your perspective, you as a conscious, sentient being are making various choices freely... we still have some degree of self-perception, we have sentience even if we are a big group of atoms that can be predicted by an outsider.
I also don't see why adding some randomness necessarily changes anything there, randomness doesn't necessarily equate to free will, just because you're no longer predictable to some outsider and some things in the universe are unknown...
*like supposing everyone believes indeterminism and decides we're theoretically predictable to some outside observer and everything that will happen could, in theory, be known in advance... it's not going to change that as individuals we'll hold each other accountable for actions etc... a mass murderer who gets caught is still going to be locked up etc...
