I understand your central idea concerns Pascal’s wager, however in terms of an answer to your question, I don’t think you need to resort to trying to remember Pascals wager and apply it to every situation that occurs in life. Making decisions and acting on them needs to be more spontaneous than that.
The Buddha tells you to think clearly about the consequences of your actions before you act - something most people fail to really ever do before acting, thanks to a lack of mindfulness. They are only aware they have acted after the fact, they do not think through the consequences and potential outcomes, they just act on instinct, emotion or conditioning - automatic pilot. It’s how most of us act, most of the time.
In order to do what you want to do - consider the potential actions open to you, the outcomes of those actions and the probabilities of the various potential outcomes - requires thinking about not only the required actions and potential consequences of any act (including not just the intended consequences but also the unintended - which you can never really be sure about) but also requires considering the likelihood of any particular outcome actually occurring from low to high.
Trying to do that in real life is probably not going to happen. You will have to find some way or develop some mental process or system of thinking to work it all out logically and in reality you are not have the time to think through all the probabilities through properly for starters and there will always be something you haven’t considered, something from left field at the time, but obvious in hindsight.
The answer however lies in the Buddha’s teachings. Develop mindfulness in all postures. While sitting, lying down, standing, walking, eating, talking, shitting, showering, etc. You get the picture.
If you develop the mental discipline of mindfulness to that level then you can always act mindfully in the moment and you will no longer ever act on automatic pilot again, you wont time waste and drift away lost in mental reverie or unfolding day dreams, your mind will stay anchored in the ever unfolding present moment, remaining poised on the cusp of the future but firmly anchored in the present.
By doing this you will always be aware of what you are doing and can act deliberately with consideration of the potential outcomes. You can remain aware of the present moment and also be aware of impending tasks or required actions (i.e. other tasks like the washing up or mopping the floor) - or other non complex things you also have to do - you can act without directly thinking of them, remaining centered in the present.
For more complex tasks, allow the task itself to become the object of focus and awareness. Your mind has room to do all this when it is not occupied with the never ending stream of mental commentary and inner dialogue. You turn that off by practicing mindfulness until it is an automatic habit.
Through making your mindfulness strong and constant you will then be able to develop strong samadhi while sitting in meditation, so from having strong mindfulness - especially if you can maintain it at all times, then when you sit in meditation you will be able to develop strong samadhi. From having strong samadhi you will be able to gain powerful insights from practicing vipassana - from asking the right questions of the mental stillness you learn how to act in difficult situations without gaining any negative karma.
Therefore (in short) to end a very wordy reply, to find a practical way of weighing up the options to you need to consider in any situation that you could apply Pascal’s wager to in real life, perhaps the best option available to you is simply to do what you are already doing - to further develop your practice of the path.
