To find the probability that Serenity will pick up the blue marker, we first need to determine the total number of markers she has. Serenity has the following markers:
- 1 green
- 1 red
- 1 black
- 1 blue
- 1 yellow
- 1 indigo
- 1 orange
- 1 violet
Counting these, we see that Serenity has a total of 8 markers.
The probability of picking the blue marker is given by the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
In this case, the number of favorable outcomes (picking the blue marker) is 1, and the total number of outcomes (total markers) is 8. Therefore, the probability is:
\[ \text{Probability} = \frac{1}{8} \]
So, the probability that Serenity will pick up the blue marker is \(\frac{1}{8}\).
