One thing I would add: You could use an integer linear programming (ILP) solver to find the subset of days to retry that maximizes the expected reward. You'd predict the probability of success on all days in the horizon using the ML model and then feed those probabilities into an ILP framework (e.g., PuLP).

The case study question was far more useful than the answer given by him(Miguel). I would ask any data scientist looking into this comment to answer this question in his/her own words. Thank You
