I want to make a roulette. When the user rotates the roulette, there is a 10% chance of 10 coins, 20% chance of 1 coin, and 70% chance of losing. How do you make harmony? Is there a way to put this function in the thunkable?

Set app variable outcome to random 1 to 100  
If app variable outcome \<= 10 then \_\_\_\_\_  
elseif app variable \<= (10+20) then \_\_\_\_\_\_  
Elseif app variable \<= (10+20+70) then \_\_\_\_\_

These conditions are in the following order:  
10%  
20%  
70%

Also, here’s a similar method with a screenshot of blocks:
