the digits 1-3-3-1-2 can be arranged into _aways math​

Sagot :

Answer:

30 ways

Step-by-step explanation:

Total number of digits is 5.

5!=120

If every digit is distinctive to each other, the number of ways you can arrange it is n!. But if it has x number of a digit, y number of another digit and so on. The number of ways you can write is n!/(x!y!)

So for the question, we have two 1's and two 3's.

That is

[tex] \frac{5!}{2!2!} = \frac{120}{4} = 30[/tex]

Therefore, it can be arranged in 30 ways
