Permutations, Combinations & Probability (14 Word Problems)
Learn how to work with permutations, combinations and probability in the 14 word problems we go through in this video by Mario's Math Tutoring. We discuss factorials and how to simplify factorial expressions as well as the fundamental counting principle. We also discuss the formulas for nPr and nCr as they relate to permutations and combinations. We go through different ways to approach these problems.

The hero we need, but the hero we don't deserve....THANKS A TON!!!!!!!!!!!!! YOU ARE A LEGEND, AN ANGEL FROM THE SKY
not me prepping for quant interviews with this video lmfao. ur a life saver bro thank you
Thank you so much for taking the time to make these videos! You're an incredible teacher, wishing lots of positivity your way 🙏👏
I just want to thank you for your permutation and combinations and probablity videos. I've watched all of them and they're the best videos on KZread that finally helped me understand truly what they are how to approach and solve them instead of plug and playing the formulas. Thank you!
Thank you so much for taking the time to post these videos. Your teaching style is very effective - exactly what I was looking for.
Hello Mr. Mario I appreciate you making your videos, as they have helped me learn during this pandemic, I hope you have a good day :)

I'm truly thankful people like you exist!
6:50 Number 4 is not complete. Unless the question is vague, I understand you mean grouping 20 players into teams of 5. This is actually very common in soccer training - forming, maybe 3 teams of 6 each out of 18. These teams would then train seperately. Without restrictions, The first set can be chosen in 20C5 ways (leaving 15), the next can then be chosen in 15C5 ways, the third set in 10C5 ways and the final set of five players form a team in themselves (that means there is no selection to be made, 1 way). Total selection is 20C5 * 15C5*10C5 = 20/(5!5!5!5!)
Even though permutations and combinations can be really tough, but I find it interesting as this topic can be easily relate to the real life situation. Definitely one of the best explanation Mr. Mario 😇

and you had to mention that they are tough - don't shape your perception as if you are doing something unprecedented instead keep it easy and fun for better learning - unnecessary stress from performance anxiety and perceptive load & hardship decreases productivity alot
really great video to solidify your understanding of the fundamentals of probability. thanks, Mr. Mario !!
Thank you! Youre helping me feel calmer and more confident about my mid term exams coming up! Thank you again!
Very helpful! Thanks much for putting this together. It's nice to have problems to pause and work and then compare the answer, and more importantly, the thought process.
Your explanation and each example are very helpful and easy to follow. Thank you so much for a meaningful lecture!
Thank you so much for doing this video! Combinations and permutations were two concepts I never felt taught how to apply. This video will help me a lot with standardized testing!

this one is the hardest in basic math I just can not understand but memorize the ways to solve and I believe even the ones who made questions can not solve other new quizzes cause I never seen someone on YT can explain them clearly
I am so glad that your videos exist!! Thank youuuuu
This one actually teaches you how to do a variety of permutations and combination questions as related to probability! Nice! All the other ones I've seen don't do that. They do an easier question similar to the one at 14:17 and end it at that.
Awesome Awesome Awesome, exactly what I needed!
the 14 word problems is what brought me into this video! thank youuuuuuuuuuuuuuuuu!!!!!!!!!!!!!!!!!!!!
thank you, Mr. Mario. the videos are great and the action of going through 14 unique questions really helps as you explain with much clarity.

Thank you Mr. Mario! Loved the video, the geometry problem and the circle problem were challenging...
This is a good intro or review of this stuff. Very helpful. Thank you!
Thank you! I am relatively good at math however, the way this is being taught to me by my professor is almost like rocket science. There is no room for asking questions because the professor will belittle you. Your videos help tremendously and allow me to feel a bit more confident!!

Great video! I think question 4 can also act as a good example for replacement/non-replacement probability, as well as the order in which the specific cards are chosen.
A very clear and detail video. My concept is cleared. thank you.
