Recalculate the values of the binary classification probabilities based on the threshold

Viewed 20

I have highly imbalanced data so for binary classification I convert probabilities for 1-class with threshold = 0.06.

I want to show probabilities to management so I need to adjust then on condition that 0.06 is my new 50% boundary.

So I want my low probability, like 0.045, 0.067, 0.01 values to be recalculated to be higher percentage.

I guess I should multuply it, but I don't know how to find the value.

data for reference
