These were so easy, I thought there must have been some hidden deception I wasn't getting. I spent two seconds coming up with the answers and about two minutes wondering what I was missing.

[theadsheep]

These problems are definitely not designed for 15 years olds. Aren't they way too easy?

[maybemaybemaybe]

😭 There's no way that these questions are made for 15 year olds. They're too easy. I wish those kinda questions appeared on my exams.

* sees it is not *

The difficulty in the two questions lies in the fact that they are so simple, you spend an unreasonable amount of time in wondering where the 'catch' is.

[ElliotSveum]

Pretty sure there was 0 people on the train. You know, to begin with.

[paolaserranosantos]

I solved both in a total of 10 seconds. I'm 63 years old, and it's nice to know that I still haven't become an adult yet!

[chinmaykulkarni]

Okay, I don't believe that 25% and 46% people missed it.. These are most easy questions there can be..

[shikikan]

Wait, THESE are the questions that are designed for 15 year olds there? We did these when we were 8 years old...

[ibreathexcellence]

I can guarantee this is not what 15 year olds are doing, this math at a 5th grade level tops. 15 year olds will be taking trigonometry or calculus

For question 2 I went: "420 divided by 20, simple, 21!" Because I'm so used to rolling d20's

Then you started explaining the answer and I realized while TECHNICALLY I was right because they never specified the amount of sides an ordinary die has, that the question was referring to a d6.

I quickly changed my answer to 70.

[greenjelly]

If the internet is anything to go by, I am a genius beyond compare!
On the other hand, these simple "puzzles" could be shared for the sole purpose of making idiots think they are smart.

[angietea]

Dude, a 10 year old can figure this out. I mean, im 13 and i did it all in my head.

[manuelf]

What the hell? I didn't find these questions 'stumping'.

[somethingsomething]

Hehe im 74 and I'm able to solve it

[ahpacific]

Nobody should be proud that they got these right. If he is right about the percentages of people that got those wrong, that's very scary. I like how he didn't even use a variable to solve first problem because he probably knew it would confuse people who got it wrong.

[nathana]

420 is a pretty high number of dice to be rolling ;)

[martinshoosterman]

I dont get how some people can't get these questions.

[asterix]

In question 2, "an ordinary, fair dice" might be unclear to US audiences as a single unit is called a "die", so the question should read either "an ordinary, fair die" or "a pair of ordinary, fair dice", both of which would result in different answers. "Dice" as a sigular noun is, however, common in the UK, and these questions were asked of UK adults, so it makes sense.

[sinecurve]

I am curious what errors these 25% and 46% of adults committed when attempting to solve these problems. Would you elaborate on this, please?
