General question about probability and counting (1 Viewer)

[QZP]

Is there a way to be consistently correct or confident in answers? In an exam there's no way to check if you missed a condition in your solution and so if your brain is not thinking right then that's such an easy way to lose marks... I really hate it

in all srsness; it just comes down to practice. If you've studied and know what you're doing then it should be good. I tend to find with a lot of my students; the ones that haven't studied are more prone to less confidence in your answers

or maybe you're just a worried person like me but this passes

One technique you can use is to try a question with smaller numbers so that you can actually count the outcomes. Then see if your method would give the number that you counted.

But you have to be careful that you don't choose numbers that bring about a special case, or that remove complications that are involved with the larger numbers.

I'd say like anything, if you've practiced something enough, you should be able to tell if your answer/result doesn't look or feel right. I used to often step back (in exam situations) and think contextually, does my answer make sense. If I could reason it out in my head (as if I was explaining it in person to someone who had no idea), would I be able to convince them of my answer? If not, I'd re-do it.

Practice → High accuracy → Confidence → 99.95

I see you left no room for ability in your equation.
