Permutations where letters are repeated in a word : ExamSolutions

[@oneinabillion654]

Now I know how and why dividing eliminates repetition. In the past, I'm always just remembering this.

[@oyindenyafatarakeme]

only video i've seen so far on youtube that explains why the formula is the way it is. Thank you

Is this video an example of "Order matters, repetition allowed" ?? Confused.

YEE

[@this.channel]

Hi, in the second example I get 2177280. 9! / 2!x3!x2! What did I do wrong?

[@fernandolobo8297]

You need to use brackets when making fractions with many numbers. Otherwise the calculator (if you use one) will just merge everything together. Like this: 9! / 2! × 2! × 3! As opposed to 9! / (2! × 2! × 3!) Hope this helps!

[@ibrahimmansoor5286]

Not at all if you speak to my wife and friends.

Beautifully articulated and reasoned through. I like how you gave a reason as to why you're performing each step.
