Pedagogic Logic: Conundrums, Puzzles, & Riddles

I’ve always enjoyed brain teasers, puzzles and paradoxes. What at first may seem pretty straight forward, can trick us into believing the illogical and outright insane.  There are many reasons for this.

 

Here is a series of puzzles, where the answer may not always be as obvious as it seems.

I will only reveal the answer, so it’s on you to solve each riddle.

Using your logic, be your own pedagog.

Take your time. Some of these are very difficult!

The answer is 35 because banana(15) + onecherry(5) x apple(4) = 35, Remember PEMDOS

Video on this puzzle above.  This is a difficult one.

This next one is even more difficult. People will come up with all kinds of different answers, most of which are wrong.

21 is the answer

How many times does the letter f occur in the sentence above?

Here is the solution.

 

The Monty Hall Problem

Suppose you’re on a game show, and you’re given the choice of three doors. Behind one door is a car, behind the others, goats. You pick a door, say #1, and the host, who knows what’s behind the doors, opens another door, say #3, which has a goat. He says to you, “Do you want to switch to door #2?

Is it to your advantage to switch to door # 2, or does it not matter?

The Monty Hall problem is a brain teaser, in the form of a probability puzzle, loosely based on the American television game show Let’s Make a Deal and named after its original host, Monty Hall. The problem was originally posed (and solved) in a letter by Steve Selvin to the American Statistician in 1975

Yes; you should switch. The first door has a 1/3 chance of winning, but the second door has a 2/3 chance. Here’s a good way to visualize what happened. Suppose there are a million doors, and you pick door #1. Then the host -who knows what’s behind the doors and will always avoid the one with the prize- opens them all except for one door  You’d switch to that door pretty fast, wouldn’t you?

Most people are convinced that after the host opens one of the doors, that it is a 50/50 chance.  But they’re wrong.  The host of the show knows where the car is, and he’s always going to open a door with a goat behind it. This changes the problem completely. The nerds call it ‘conditional probability.’

Another way to look at it is this.  In the beginning , you have a 33% chance of winning the car.  So if you pick a door and stick with it, how could you odds increase to 50%? They can’t.  If you stay you have a 33% chance of winning.  And if you switch to the other door, you are basically getting a 2 for 1, since he’s always going to open the door with a goat behind it.

Most people don’t want to jinx themselves so they stay with their original decision.  Game show host Monty Hall understood this, and probably saved a bunch of money he’d otherwise have to spend on expensive cars, but overall I guess your decision ultimately comes down to if you want to drive home a new car or have a goat’s lifetime of raw cheese and milk.

The Pareto Principle

This is a weird phenomenon that happens whether you like it or not. I’m looking at you, you 1% pharisees.  What I mean by that is there are always going to be people who criticize those whom are successful. Think about it.  There will, and always should be a certain portion of the population that are more successful than others.

The Occupy Wall Street folks in recent years have coined these people the One Percent, and let me tell you, they are just evil, so freaking evil! (insert sarcasm)  They are so evil because they work harder than others in a world where everyone is ostensibly equal in every regard. The only problem, people are not innately equal in every ability. Some are better at this, and others, at that.  It’s ridiculous to believe in equality as the liberal media implores us to do so.

This principle proves inequality. For example, at any warehouse, 80% of the workers will be lazy and only accomplish 20% of the work.  Conversely, a small fraction of the workers, 20%, will do about 80% of the work.  At a used car lot, 20% of the salesmen sell 80% of the cars. Etc..

80% of NBA players will score only 20% of the points, and vice versa.

The Pareto principle is a principle, named after economist Vilfredo Pareto, that specifies an unequal relationship between inputs and outputs. The principle states that 20% of the invested input is responsible for 80% of the results obtained. Put another way, 80% of consequences stem from 20% of the causes. -Investopedia

This can apply to anything really.  There are multiple youtube videos that can explain this better than I, but suppose you have a blog called joedubs.com.  Only 20% of your subscribers are going to comment on your articles.

Here is another way to look at it; of those 20% of people who actually do comment on the blog,  Joe is only going to respond to about 4% (20% of 20%) of the comments.

Jordan Peterson outlines this principle in regards to human productivity.  20% of the population does 80% of the work.

 

Zipf’s law

Zipf’s law was popularized by George Zipf, a linguist at Harvard University. It is a discrete form of the continuous Pareto distribution from which we get the Pareto Principle.

According to wikipedia Zipf’s law (/ˈzɪf/) is an empirical law formulated using mathematical statistics blah blah blah, blah, bla ,blah blah bla…  Let me just give it to you straight instead of trying to impress you, as every single wikipedia entry seemingly attempts to do. I hate wikipedia sometimes.  Just ignore it, and go to the next few entries of google.

V Sause says:

For some reason, the amount of times a word is used is just proportional to one over its rank. Word frequency and ranking on a log graph follows a nice straight line. A power-law. This phenomenon is called Zipf’s Law and it doesn’t only apply to English. It also applies to other languages, like, well, all of them. Even ancient languages we haven’t been able to translate yet. And here’s the thing. We have no idea why. 

Ok, now even that is not clear.  Let me break it down in quantum mechanics using the zygote differendim for π squared.  I’m just kidding; that is a bunch of bullshit too.

This is the transcript of the V-Sauce video.

 

In Conclusion

Sometimes we are so sure of ourselves; our hubris and ego kicks in full swing.  We feel like we can’t possibly be wrong because we’ve thought of everything.

But sometimes, I am wrong. I definitely did not answer these all correctly at first glance. I’ve been wrong before. I bet you have as well.

These conundrums are pedagogic puzzles to understand our own psyche.  We’re very seldom correct all the time, or even most of the time.  Do the math. The more aware of how unaware we are, the more understanding we have to gain.

  1. So what are the answers to the puzzles?

  2. Well done mate. Answers to riddles are 14, 101, 50, 16.
    I knew about pareto principle thanks to Jordan Peterson.
    Allegedly 97% of our “junk” DNA follows the pattern of Zipfs law.

    • You got one of them right. I updated the article so you can find out the solutions. As far as junk DNA, I think that concept is kind of silly. Dawkins is a turd in my humble opinion. But yeah, Zipf’s law does pop up everywhere. Thanks Epik.

  3. I agree, i just know it under that name therefore I’ve put it in quotation marks. Dawkins is pretty lame. Pitty he didn’t faced the real chalenges from Sheldrake & Hancock.

What do you think?
