[+] -10 points 2 years ago* (2 children)

Booooo

This video didn't give the correct answer in any place reasonable. I just wanna know the answer before you go off on an 18 minute lecture.

To anyone who just wants to know the answer without watching the whole video, the correct answer is 4

    He spends the first 5 minutes explaining the answer is 4, but the question was also worded ambiguously that 3 and 1 can also be correct answers.

    Maybe watch the video, it's more interesting than you'd think

    How did this video stretch out to 18 mins?
    I remember a mindyourdecisions yt video about this from several years ago that showed it in a couple of minutes and why it is n+1.
    sorry i don't remember the url though.

    It explains the answer is 4 before the 5 minute mark.

    Part of the reason is because it goes into the story of the SAT being wrong and a student being the one to catch it, which I found interesting.

    After that it mathematically proves it several different ways and then shows how it relates to some real problems in astronomy.
