a dice is thrown three times .
Calculate the ways to get at least two sides are equal
soluation
90+6=96 Is it true solution
or
30+6=36 Is it true solution

thinks ,pka
why to use “permutation” and did not use the "combination

What do you mean by "at least two sides"? What do you mean by "equal solution"? Are you maybe asking about determining the number of ways that, in three throws, you could obtain the same value on two or on all three of the throws?

I'm sorry, but I have no idea what this means. Are you maybe using a non-standard die, so one of the sides has "90" as its value?

The word dice is plural. We throw a pair of dice.
The word die is singular. We throw a die three times.

There are \(\displaystyle \bf{6^3=216}\) total ordered triples that result.
Of those \(\displaystyle 6\) have all three entries the same. Can you explain that fact?
There are \(\displaystyle \mathcal{P}^6_3=(6)(5)(4)=120\) triples of three different sides. Explain!

Now, you put this together and give us the answer.

Thanks

why using the “ Permutations doesn’t combinations
two sides
(6,1,1) ,(1,6,1),(1,1,6).........................
30 +30 +30 =90
three sides
6
so 90+6=96

That is an excellent idea. You ought to practice it more often.

How many ways can we award two sides similar and two different sides




How to know if its permutation or combination?
