Random text select

Hi, I have very very limited knowledge in app building and I just wanted to build a simple app for a Christmas present
I’m trying to create an app that randomly shows text blocks based on previous choices. For example, I enter the app and I have to choose between Red and Black. If I choose red, the screen would show me a random text out of a selection of 15 texts. If this is possible, how can I achieve it?

Thank you in advance, I am aware this might be a very simple question but I’m just stuck at watching videos and searching forums with no answer.

Hi
Yeah, something like that would be easy. Do you have any designs for it?
The first would be to learn about Event Actions and how to Navigate between screens
