If there are 13 letters typed, the probability that no letters will be repeated can be found to be 1.05 x 10⁻²⁰
<h3>How to find the probability no letters are repeated?</h3>
First, find the number of possibilities of 13 letters from 26 letters in the alphabet as:
= 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26
= 6.156 x 10³⁶ possibilities
If the numbers are not to be repeated then the possibilities are:
= 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14
= 64764752532480000 possibilities
The probability that no letters are repeated is:
= 64764752532480000 / 6.156 x 10³⁶
= 0.0000000000000000000105
= 1.05 x 10⁻²⁰

Based on the graph, AD passes through -30 of the x - axis and DC passes through -15 of the y-axis.
These lines are the boundaries. Point P is located within said boundaries.
Since Point P is 5 feet from AD, it is in -25f the x-axis.
Since Point P is 5 feet from DC, it is in -10 of the y-axis.
Thus, Point P has the coordinates (-25,-10). It is located on the 3rd quadrant of the plane.
First, we are going to write it like this:
Then, we are going to do something like factoring, but it's not factoring. An example would be:
If we apply it, we would be left with:
We cancel the common factors, and we are left with:
That's our final answer.
Let me know if you need any more help!
