Hey guys, I wonder how to find this math formula.

What is the FE required to be a profitable bet if :

• we bet 3/4 pot , with 10 % equity ?

and

• we bet 3/4 pot with 20 % equity ?

I know a 3/4 bet without equity is 0.75/1.75 = 0.428 => mini 42.8 % FE to be a profitable bet. But what if we add 10 % or 20% equity ?

Thanks very much
