It would be 18/20 or 9/10. You know that because you would have to subtract the two that were eaten from the 20 which is 18. So then you would have 18/20. Finally, you would simplify it and get 9/10.

I hope this helps! Have an awesome day! : D

Answer:

18/20 * 17/19 ≈ 0.805263158

Explanation:

18/20 for the first chocolate not to be coco cream

then, the number of non-coco ones is lowered by 1 and the number of total too, so

17/19 for the second chocolate not to be coco cream

The chance that neither of the 2 chocolates is coconut cream is 18/20*17/19 ≈ 0.805263158
