@fantasticcrow Yay, I'm glad that helped!! And as for counting versus probability, it all depends on what the question asked for. To give a simple example:
How many ways are there to make a three digit number where all the digits are even? [This would be a counting problem, because you want to count how many 3-dig #'s there are where all the digits are even]
If you choose any three digit number at random, what is the probability that all its digits are even? [This would be a probability problem, because you're asked what the chance of something happening is-- so in this case, you would take the answer from #1, and divide by how many three digit numbers there are!]
In the context of this problem, we can't use simple counting because not all of the options are equally likely to be chosen. In other words, you should use counting when all the options are equally likely ("weighted")-- for example, choosing a three digit number at random. But in this case, they're not, so we have to actually multiply out probabilities, if that made sense.
@dazzlingrobin I don’t think it’s possible to skip. You’ll have to randomly select answers for each of the videos and get at least 60% on the weekly challenges in order to continue. It shouldn’t take too long to do that. You can also contact the mods and see what they can do but that’ll probably take longer.
@tidyboar I do agree that there are a lot of windows to click through, and it can be inconvenient sometimes! Since we are using a third-party platform to host our courses, there unfortunately isn't much we can do to change the interface. But I will pass this along as a feature suggestion to the company that manages the site! 🙂 Thanks for your comment!
