You are very good at explaining this! I’m studying for the GRE and its crazy how much how someone teaches a math concept makes a difference! There was a few things you wrote on the white board though that I wish were a little more legible :P
THANK YOU so much. I've been soooo confused over this and I'm halfway through your video but I already understand it. I was really confused at the formulas but you've explained it so well. i love how you simplified it. Thank you once again.
You’re welcome Ann! If you need more help check out this other video I did here: Permutations Combinations Factorials & Probability ua-cam.com/video/TBnPkKxXPu8/v-deo.html
I enjoy your videos so much, you explain clearly and get straight to the point. I have an EOC coming up for Algebra 2 and the only way I know I’ll be familiar with problems is through you! Thank You! ☺️
Glad my videos are helping you! For help with your EOC you may want to check out my Algebra 2 Midterm review video and my Algebra 2 final exam review video.
thank you! i used this to study for my science ged and i ended up passing with 186! your explanation of the difference between combinations and permutations was the only explanation that clicked with me. thank you!
This video was a lot more fast pace compare to the beginner ones that I've watched prior to this. I chose this video on purpose to see how fast I learned the formula for each one and see how well I can solve each equations without looking at the formulas afterwards. I really did enjoyed it.

Glad you liked the video Jamie! Here is a more recent one I did if you want more examples: Permutations Combinations Factorials & Probability ua-cam.com/video/TBnPkKxXPu8/v-deo.html
Taking a Lib Arts Math in college, 20+ years after graduating high school and never having taken more than basic math. You are a blessing! The last question was cut off short, I really wanted to see how it was figured. But I will look at your other videos for sure.
hello sir,i am a student from bangladesh and i have been stuggling for quite soome time on PnC due to lack of concepts and the fundamental basics but today you have solved all of my problem so thanks a lot sir.
Mario, thank you so much for the clear video. I've spent the last day trying to find a good explanation and this is definitely the best one. Appreciate the effort! Mike
Mario, I am sorry to ask but I would love if you could help me with this question. "Last week ABC Company's stock had 3 advances, 1 decline and 1 unchanged (total of 5 trading days). In how many ways could this set of outcomes have happened?" I know that this would be a permutation because of the fact the order does matter. Do you have a video that explains how to do this calculation? I would really appreciate some guidance on where you could send me for assistance with that! Appreciation from Canada, Mike
@@mikef9677 Hey Mike the answer is 120. You can either use the fundamental counting principle, or the given formula to find no. of permutations. Either way, because we have 5 factorial ways, hence 5! = 5*4*3*2*1 = 120, or input the numbers into the formula as follows, 5P5 = 5! / (5-5)! which is 120/1. Hope you can finally pass your class now after 3 years lol!
4:22 but when order is important dont we use permutation, which you did but in permutation add amd in combination we multiply? pls tell huge test on the way!
Thank you so much... already, in the first minute of your video, you have made it more clear than my terrible teacher has in the multiple weeks of class. I have an exam tomorrow and was stuck on how this works, but this helped a lot!!
Hi can you help me with this question? The question is: In how many ways can the letters of the word "EXCELLENCE" be arranged if (i) the four E's are not all together, (ii) the four E's are all seperated?
Germaine Loi I think for (i) you meant together? If you did I think you would treat the E’s as one unit so it would be 7 groups instead of 10 therefore it’s 7! For (ii) if they must stay separate then you would take 10! Which are the total possible combinations and subtract 7! Which represent the ways E can be placed together I’m not sure if this is 100 percent correct but this is how my teacher showed using class :)
To teach this stuff you have to understand it at a fundamental level. I don't know why you chose to teach it instead of becoming an engineer, but we're all better for it.
What about if we are required to have an order like 3 letters with 4 numbers let's say they're vehicle plate numbers? Example : ABC 1234, BBC 3781, DDD 4461, FFF 5555, etc? How many ways we can have that format from 26 letters and 10 numbers? Condition 1: Letters and numbers may be repeated, Condition 2 : Letters and numbers may not be repeated as shown in those examples. Thank you in advance for the reply.
Hi Mario Perhaps you may be anle to help me with a combinations problem I am trying to solve. I am not having success. I have a group of 10 numbers. The combinations of 3 of those 10 numbers is 120. The combinations of 3 from 5 numbers is 10. My theory is that if I take 12 groups of 5 numbers from my 10 numbers then I should be able to contain all 3 number combinations of my original group of 10 numbers in thses 12 groups of 5. Can you help. I have been successful with similiar. I have 30 groups of 5 numbers that contain all combinations of 2 numbers from 25. I have also been able to get 14 groups of 4 to contain all the 3 number combinations of 8 numbers. I just cannot get any progress on my 10 number problem. I would really appreciate any guidance or a solution.
If I have 6 books, all of which are about different subjects, but 3 are RED and 3 are BLACK. How do I decide which permutation to use if I want to deduce the probability of a red or black being the next colour to come out. I ask this question in relation to Roulette, where you can bet on either red or black, knowing that the colours are only one attribute of the individually numbered possibilities.
sir... your teaching method is awesome, but in the last question it is 50!/47! , but by mistake you wrote 50!/47! 3! which is incorrect... please correct it... jai hind
That is a repetitive Variation and not repetitive combination formula! the right formula is N!/(R1!*R2!*...*Rn!) where Rn is the element that is repeated by Rn times, N is the total number of elements and n is the index of the element that is repeating.
I can understand other solutions such as 7C3, 12C7 but I cant seem to solve 32C18 × 3P2 ... the answer I got was 4.713 and 6 which is equals so ??? But the real answer was 4960 × 153 = 758 880 😥 Im CoNfUsEd
If replacement is allowed then the events are independent and the probabilities will remain the same however if it is without replacement the probabilities will change because there are less items to choose from.
Can somebody help me out? So there was this one question and it said someone is only able to choose on option of each cones cakes and cookies and each of the three had different types of cones, cakes and cookies and the questions is how many combination can you make of each? So do I use this same formula as the video or what do I do HELP PlS

for the 2nd question..my guess is that 19C2 or (19,2) is right becaus in a team there will be a captain so we can't pick the captain to be a co-captain. Anyway, wonderful class thank you
