Answer: 0.68

First, we list down all the letters that represent 1 point.

We have:

A: 9 tiles

E: 12 tiles

I: 9 tiles

L: 4 tiles

N: 6 tiles

O: 8 tiles

R: 6 tiles

S: 4 tiles

T: 6 tiles

U: 4 tiles

Then, we will get the total number of these tiles:

[tex]9+12+9+4+6+8+6+4+6+4=68[/tex]

Next, since there are 100 tiles in total, we will divide the number of tiles worth 1 point by 100:

[tex]\begin{gathered} P=\frac{\text{ number of tiles worth 1 point }}{\text{ total number of tiles }} \\ P=\frac{68}{100} \\ P=\frac{17}{25}=0.68=68\% \end{gathered}[/tex]

Therefore, the probability of picking a tile worth 1 point is 0.68.
