Permutations, Combinations, and Probability (15 Word Problems)

In this video lesson we go through what a permutation and a combination are and how to use them to calculate probabilities in 15 word problems. We discuss the formulas for nPr and nCr as well as n! We also discuss binomial probability in one of the problems as well as probability problems involving a standard deck of cards.

Amazing tips Mario! In number 2, what would the answer be if ties were possible?

[molinyang]

Sir, you are better than all my math professors at college at clearly explaining math concepts and showing how the formulas work

[soeunjeon]

Thank you so much Mario! I just have one question: why do we subtract 1 before we calculate?(number 8, salade bar question), every question that contains 2 possibilities (yes or no), do we need to solve in the same way like you did? (2^n - 1)

[salmanel-farsi]

A fanstastic collection of probabilty questions which span several concepts. Q14. Ironically combination lock means order does not matter. They should really call them permutation locks.

very helpful, i would recommend it to anymore.

[jaineilsart]

The part with the cards is one of the hardest because i dont play that game since it's really for grownups. I keep messing up since i dont understand the fundamentals of the game. But i still understood some of the materials so thank you.
