Well, very disapointing,

The fruit roll problem: The theoretical probabilities, P, of Winner, Loser, and Try again are: P(W)=5/5^3=1/25=4%, P(L)=(5 * 4 * 3)/5^3=12/25=48%, and P(T)=1-(P(W)+P(L))=1-52%=48%. Attached file FruitRoll_GDorfman_9apr22.nb contains two items: (1) An alternative module for the problem that avoids using Which, Switch, etc., together with code to output 30 executions of it (2) A simple Monte Carlo analysis that supports the theoretically computed probabilities.
A solution for the Fruit Roller using the functions Tally and Switch.

When I downloaded the Course Materials at the End of the Last Day of the Course, there does not seem to be any of the Week 3 notebooks. Week 1 and Week 2 notebooks are there, but not Week 3.
There seems to be no new files added since Apr 1 (hmmm, All Fools Day?). Were any new files added more recent than Apr 1, and somehow I'm downloading the wrong cache of files?

Hi
I'm in process of my review for the 5 Quiz Marathon. I think it is reasonable to ask whether each Quiz covers a certain portion of the Course? Said Info would make my prep more efficient, since we covered and entire Book in 2 weeks... I would expect the 1st Quiz would cover perhaps the first few Days, while perhaps Quiz 5 might be expected to cover the entire course? or is there some other portioning that you would be willing to share? I would happily accept the answer in the form of a Wolfram Language Association Assignment that would lead to a set {<| "Quiz 1" -> {1, 3}, "Quiz 2" -> {3,5}, ... or some such association of
Quiz # -> {Day1, Day2} Thanks In Advance

I found at least one answer for 2 of the Questions on Quiz 2 was "close" to being correct, but actually all of the offered answers for these 2 Questions still contained some errors where they would not evaluate properly. I'm guessing that each person receives a set of different Questions on their Quiz 2 that they are confronted with; the Questions being extracted at random from a Pool of Test Questions (a New Wolfram Language Function: RandomQuestion[10]??). Anyway, I'm not particularly bothered, as I passed it anyway, but would like to describe the particulars so as to contribute to an improvement in the Pool of Questions. For obvious reasons, I realize it might be best not to discuss this openly in this forum. Is there an email that I can send the 2 Questions, and what I believe is incorrect as to the offered answers? Also, it is suggested -in the Quiz- that to get the Certificate, you must get 60% score...I'm thinking that what is meant is the the score should be 60% or greater, otherwise I would have had to go back and change 4 of my answers to reduce my score back to 60%? Overall, it's been Fun so Far. And I do appreciate the effort that the Gang at Wolfram has made in offering this course.

Is there a better way to turn a list of associations into a single association than is illustrated in the following example? ((In Mathematica, the Entity[...] entries are the usual icons, which are more readable.) assocList = {<|Entity["City", {"Kabul", "Kabul", "Afghanistan"}] ->
"Kabul, Afghanistan"|>, <|Entity[
"City", {"Maarianhamina", "Aoland", "Finland"}] ->
"Maarianhamina, Aland Islands"|>, <|Entity[
"City", {"Tirana", "Tirana", "Albania"}] -> "Tirana, Albania"|>};
Association@Flatten@Normal[assocList] Here is the output: <|Entity["City", {"Kabul", "Kabul", "Afghanistan"}] -> "Kabul, Afghanistan",
Entity["City", {"Maarianhamina", "Aoland", "Finland"}] -> "Maarianhamina, Aland Islands",
Entity["City", {"Tirana", "Tirana", "Albania"}] -> "Tirana, Albania"| >

Hi!
Merge[assocList, Total]
Should do the same thing :)
|
|
|
Hi Gerald, This is probably the easiest way if there are no duplicate keys
Association@assocList
|
|

Why does an association with 2 rules behave differently than an association with one rule in this example:
In[98]:= {Reverse[<|a -> {2, 3}, b -> {4, 5}|>, {2}], Reverse[<|a -> {2, 3}|>, {2}]} Out[98]= {<|a -> {3, 2}, b -> {5, 4}|>, <|a -> {2, 3}|>}

Is anyone else having a problem going to the link for Quiz 1?. See attachment for the returned error. I get this error using both Chrome and Safari browsers. I get the same error when I try to open "An Elementary Introduction to the Wolfram Language".
Is it one of the 17 solutions for the fruits roller?

very cool! I haven't seen this one before, nice job

nice! I love that you combined our learning on manipulate with this project!

this is awesome, I love the triangles!

Me too, although now i see the missed opportunity for the nice joke "I love squares"

Half way through week 1! How are we enjoying the class so far? What have you learned? What's been hard or surprising for you? Here are some of the things we've created together in the last couple of days:
 Share your own creations!

I missed the start of this one, but I'd be interested in joining the next iteration.
