Question

How solve it?? How many points of three coordinates (x, y) can be generated with the digits 10, 11, 12, taking into account that it is not possible to repeat the numbers?

PLEASE !!!!!!

Answer 1

6

Explanation:

If I understand the question correctly, what's being asked for is the number of 3-coordinate points `(x,y,z)` can be made using the numbers 10, 11, and 12 - keeping in mind that each number can only be used once per point (and so point `(10,10,10)` would not be allowed).

In the `x` position, we can place one of the three numbers.
In the `y` position, we can place one of the remaining two numbers.
And in the `z` position we can place the remaining number.

That means we have:

`3xx2xx1=6` different points.
