Randomizer for Bubble.io application -- 2

Hello. I have the included image in my google sheets script. Its function is once clicked it randomizes a number and once a number is chosen, it inputs text into the i1 and i2 fields . I would like this functionality in Bubble.io. I would like you to write me some code or teach me how to implement this into my [login to view URL] application. The core function I want this to do is once clicked, choose between Decision A and decision B based on the percentages I've provided. 25/75 and 50/50 . Once clicked 25% chance of decision A being chosen, and 75% of decision B. Then in the next one script / image / button . 50% of decision A and 50% of decision B
