Please Adjust the Card Explanation to be More Straightforward
Hi Team,
First, thanks for your hard work.
But it's confusing for someone new, who is just learning this stuff, to make Event A the second event and Event B the first. You could restructure the example to follow the logical flow of events where Event A is first and Event B is second in the card example, as this is how normal life operates.
This would take the form of P(A) x P(B|A) rather than the far more confusing form P(B) x P(A|B), which is what you actually demonstrate in the course. Both are mathematically equivalent, but the second is more confusing for this card example than the first as you basically work backwards mentally.
Again, I understand that if you're experienced it's very easy to mentally juggle this stuff. But for those of us just learning, it's frustrating to go against common sense and the logical flow of events, especially for something like drawing cards, which has a very clear order of operations. No one draws the second card before drawing the first in real life, at least, I've never met anyone who does that.

Hey Justin,
I absolutely understand your point and think this is a good suggestion. I've somehow missed this when we've created the course. Considering that Viktor is not with our team anymore, it would be a bit challenging to change this example, but we'll do our best to make the fix.
By the way, we've started to add very cool interactive exercises in each of our courses including the Probability course. You should be able to see them later today. I'd really appreciate your feedback on these. Hope this will improve the learning experience.
Best,
Ned
Thanks Ned! I really appreciate you getting back to me. All you shared sounds great. I can't wait to see the interactive exercises.
How do i access the interactive exercises? I don't know that I've seen them yet.
