Answer 2

Thank you for asking this question.

Minimum 19 time

7+ 11 =18  

18+1=19

Means the minimum time required to find this combination would be 19.

Because there are 7 pink balls and 11 yellow balls we will add them and we will get 18.

And then we will add 1 to 18 because that is the lowest possibility of getting that combination. So when we add 18 and 1, we will get 19.

So the answer to this question is 19.
