I've found someone who teaches using simplified words and a step-by-step, PATIENT, method! Thank you kindly!
Thank You. I like it when Math is explained straight forward and is self-explanatory.
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
I love how simply you explain it, and how easily I understand you!!! You're the best teacher!

You're a great teacher. Many people teach maths but not all are good teachers. You're doing a good job. Keep it up!
Thank you! 😃
Dude I've watched a few of your videos now and your very good at explaining things 👌
Man... Thank you thank you thank u!!! I hope youtube pays you way way more cause you deserve it!
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.
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
Love you sir , I was trying hard on UA-cam to understand this P and C...but your explanations was awesome.
U r a savior- u explain very throughly and i wish more teachers taught like this
Crystal clear explanation.
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, helped a lot! I had trouble seeing the difference between permutation and combination, but you made it clear.

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
Your welcome Mike. Glad my video helped you.
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!
IT FINALLY MAKES SENSE, WOO.
Glad my permutation Video helped you Royce!
it was helpful sir. thank you so much.
You’re welcome! Glad my permutation Video helped you!
Helpful video! It helped me.

Very helpful!
Thank you very much sir i really appreciate your efforts
Your welcome!
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.

You’re welcome Pitak! Glad to hear my videos have been helping you!

Glad I could help!
love from india, Thanks for clearing concept. sir
You’re welcome Ravi!
Good teacher!
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.
Thank you sir. Your explanation is better than my teacher's :p
Glad you like my explanations!
Really helpful thanks

it the second in the team their might be a captain if i am right then the two captains could be picked from 19 players right?
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
niice vid it helps me
Glad you liked the video!
Heck yes
I would llike to know who is the s.o.b. that would dislike such useful video!
Thanks Mario for your effort
Thanks Giovanni. Glad to know I’m making a difference to some people out there.

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
This concept is new to me and I understood in 7 mins. Thanks sir
You’re welcome! Glad my video helped you!
