Hi everyone!

Is there a good pattern to look for when doing probability questions, so we can decide if take the probability approach or the combinations approach?

Also, is there a checklist of thing we have to look for before we approach the question?

Like it seems that when I do probabilities I have no method what so ever, I just select an approach that seems to make sense and do it because I have something I can solve in front of me.

Thank you!

Great question.
The answer isn't straightforward. In most cases, I find that applying the probability rules is the faster approach, but there are times when counting is better.
If you're interested, here's a video that's devoted to determining the best approach with probability questions.



Cheers,
Brent
