But what if I initially picked the blue door?
Do you mind to share the name of software ?
This virtual manipulative and many others are currently located at: pcmathoer.wordpress.com/vm/
Thank you very much for this video, I really appreciate all of this. I need to study more, I need more practice and This class is very useful. Your class is easy to understand, You're a really great teacher, Keep it up.
Thank you very much. Your comment is appreciated!!
Thank you bro👍
Damn, the guy who discovered this law was cooking 🔥🔥 how do these kind of things come to mathematicians mind?
How is this this easy, my lecturer is a clown
You were very helpful, thank you for your work, you are the best
@@danidaniela2777 Thank you for taking the time to leave a comment. I appreciate it.
Noice
thanks
Can you do it across the first row?
Yes, you can use any row.
Noted that x=r*sin(theta) is a standard trigonometric substitution that conveniently gets rid of the radical… not to be confused with a rectangular to polar conversion.
I'm not sure but maybe the first answer is wrong. It should be 5 right? Since there are 5 kids and 1 swing. So 5 possible ways to line up so that each gets a single turn🤷. Or 5P1 = 5
It is correct because it is asking how many ways they can line up. All 5 students line up and the order matters.
This doesn't tell me how the fuck to read a Round Robin grid.
Thank you so much, I was having a mental breakdown trying to understand why my answer and the calculator's were different but turns out they mean the exact same thing!!
you can actually do this with only 4 functions and one list
7:17 is there a typo for x-vector / span of lambda_1? Shouldn't it be 1 to 2 vice 2 to 1?
Corrected Video: ua-cam.com/video/2R2otzs4FsI/v-deo.html Thank you for letting me know.
thank you so much
Thanks man, I had already studied the number theory but was stuck at its applications, I had my submit due today, you came in like a god’s helper in my life 😅🔥. Thank you. hope you have a nice day.
I am glad to hear I could help!
At first I thought it's real.. then I realised it's only works on programs.
Try it out with a deck of cards, works then too.
Can the index be any number, as long as the last value is adjusted in order to correspond with the index?
Online simulation: www.mathwarehouse.com/monty-hall-simulation-online/
This is only theoretical. In a practical way, if you leave your door, you'll get 50/50 to choose the right door.
@@_SweetLittleAngel_ Hi. I thought you might like this simulator. www.mathwarehouse.com/monty-hall-simulation-online/
@@Mathispower4u I stayed and got the car.
@@Mathispower4u The chances after leaving yourself with a car and a goat is 50/50, and there's no proof against it possible. Mathematically it's a complete slur.
@@_SweetLittleAngel_ Yes, that is possible. Try running the simulation 100 times.
@@_SweetLittleAngel_ Nah, you are wrong, but it would be easier for you to test the problem out to realise why.
thank you so much bro
thanks
Super sir
This doesn’t make any sense, by this logic in the same exact scenario couldn’t I pick blue and then switch to yellow?
You made the '-2' in row 2 coloumb 1 '2' at time 0:36
Thank you. I will get that fixed today.
The videos that came with my homework (online course) didn't explain what's actually going on in these types of problems and either the textbook wasn't clear or I couldn't understand it... I clicked on a few other YT videos on the subject, but watching your video is what helped me to understand--thank you!!
I am glad I could help. Thank you for taking the time to leave a comment. 😃
I tried putting in the exact thing in 2 different calculators and both say syntax error
Makes sure you are using a negative and not the minus sign if you are entering exactly as I did. If you want to use the minus, try entering 93(1/240)-5(239/240).
Can we say ".33..." equals 1/3. Like a politician, we sure can. Just don't mention we are leaving something out. ".33..." equals the incomplete and imprecise division of 1 by 3. We could also find a circular algorithm to somehow cancel out the infinity x=".33..." times 10 10x="3,33..."? plus x 11x="3.66..." divide by 11 x=".33..." the infinity is still there. How about x=".99..." times 10 10x="9.99...? plus x 11x="10.99...? Divide by 11 x=".99..." I must be doing something wrong. Can't get rid of the infinity. If I change the add to subtract, divide by 9 instead of 11, what is the mathic that gets rid of infinity.
Here is a longer version with 3 reason that you might enjoy? ua-cam.com/video/hxANwjJURg8/v-deo.htmlsi=r0mDU4CHGFHLDplN
@@Mathispower4u I addressed two of those reasons. The third is the sum of a geometric series. The sum of a finite geometric series is precise. The sum of an infinite geometric series is the limit of the sum of its partial sums. This more to the core of the controversy, infinity, and how math handles an infinity of values. A quick, intuitive refutation of the sum of infinite geometric series is to add an infinite amount of terms that have a value greater than zero and expect a precise value. What is next. The Archimedean property. A result of the property is that there is always real number values between real numbers. 1-".99..." is greater than 0. This again can be shown intuitively as true is the result of constructing real numbers in bases of Natural numbers. In base 10, ".99..." is the closest representation to the real number value of 1; 1/10^n. In each number base higher there is a real number base b closer to 1; 1/b^n. My intuition is based on high-school math basics that don't change through real number math. Also on a large number of math texts, mostly Calculus and a variety math subjects. This controversy has recently shifted to saying that ".99..." is 1 (mid twentieth century) This controversy I feel is connected to the continuum hypothesis.
why cant we just put -0.2 instead of k. because in the previous exponentail decay video (part 2) we accepted k as decay rate?

Best video, makes so much sense. Easy explanation.
One factory employs 35 male and 20 female workers. The factory owner wanted to form A social committee for male and female workers with 5 randomly selected members: What is the probability that the chairman of the committee , Vice-Chairman of the Committee and the treasurer are male workers, and the other members are from female Workers?
Thank you soo much
These videos fail to address that your door will not be removed meaning it’s safer to switch
Thanks very much, but then it means the statements are true both ways, that is, (A implies B) and (B implies A), or either (P and Q) are both true or are both false, (P and Q) or -(P and Q). So what is the negatation of this statement. Thanks
you are moving too fast and don't explain enough..
Hi It was really helpful, thank you. Which software do you use for writing?
No but the red door is not part of the options anymore so its 50 50
i think i have the best explanation. Think of it this way: there are 3 people. they all chose a different door. which means that one of them chose correctly, the others didn't. so when the host reveals the other wrong door, 2 of the 3 people will benefit from switching. meaning the chance is 2/3. hope this helped
They have a combined total of 2/3 not a seperate... If one door is removed, you remove a number from the 3..because there is no longer 3. Lets say i choose yellow door, if its right and i switch to blue , i lose a million
If you have common sense and a basic understanding of logic, the chances are now evenly distributed between the door you originally chose and the door you switch to
i think i have the best explanation. Think of it this way: there are 3 people. they all chose a different door. which means that one of them chose correctly, the others didn't. so when the host reveals the other wrong door, 2 of the 3 people will benefit from switching. meaning the chance is 2/3. hope this helped
"If you have common sense and a basic understanding of logic" agreed. People who only have a basic understanding of logic will assume it's 50/50. However those of us with a better grasp of logic will understand that switching wins 2/3 games.
mine doesn't give me the answers your did fir the first problem it just gave me -5
Omg thank you soo muchh
It's 50 50 lil bro
