Enable button based on some rules

Hi, I don’t have much experience with UiPath and I need some help regarding the UiPath forms. So I have a table which contains 3 columns: question, answer and check. The first 2 columns are read-only and the last one is a select boxes component with 3 values: correct, wrong, unknown.
Let’s asume that in that table are 5 questions. The user should check if the answer is correct or not. If there are at least 3 questions that were checked as correct I want to enable the "Validation Successful " button and otherwise to enable the “Validation Failed” button. How exactly I can achive that?
