feasibility + to do smth or + of doing smth

[Jack8rkin]

Hello everyone!

Please help me with the right form combinable with the word "feasibiity".
Is it:

1) feasibility + to do smth (infinitive)
or
2) feasibility + of doing smth (gerund or noun)
or
3) both are possible?

Thank you

I was told that "possibility" is always +gerund (or noun). Is it the same with "feasibility"?

I would stick with 'the feasibility of doing something'.
