ASK chances condition (1 action that can trigger more than 1 event with different %)

[mdeath]

good evening, i want to ask a question.
so my problem is like this:
the plan is when i am pressing red button, there is a chance normal enemy will spawn or boss will spawn.
and i want the chances to be different, like 80% normal enemy will spawn and 20% boss will spawn.
i tried using x chance out of y at random with 2 event like this

-user click with left button on "red button"
-8 chances out of 10 at random
) enemy will spawn


-user click with left button on "red button"
-2 chances out of 10 at random
) boss will spawn


at first i thought it was fine, then when i am tried it again and again i realized sometimes the event can overlap and spawn enemy with boss
i am new as you can tell, maybe there is a better option to make 1 action that can trigger 2 event with different percentage like my explanation above
any help will be much appreciated

If you use a value and set the value 8 out of 10 times then you can control that only 1 enemy is created - the rest you were doing right.

I've attached an example for you - it's easier than explaining it.

Here is an example on how to use a string object as a random "pool". You populate this pool by editing the string. It's quite flexible, just make sure you don't use numbers greater than 1 place, i.e having "1" and "10" or "11" in the same string will cause problems. You can use letters along with numbers if you wish.

both works like a charm!
thanks for your time @Janette5 and @casleziro and also giving me the examples with good notes and explanation.
hope the best for you both
