number of desired outcomes
-------------------------------------- ____
total outcomes

Answer 1

To determine the probability that Serenity will pick up the blue marker, we can use the formula for probability, which is:

\[
\text{Probability} = \frac{\text{Number of desired outcomes}}{\text{Total number of outcomes}}
\]

**Step 1: Identify the desired outcomes.**
- The desired outcome is picking the blue marker.
- There is only 1 blue marker.

**Step 2: Identify the total outcomes.**
- Serenity has several markers: 1 green, 1 red, 1 black, 1 blue, 1 yellow, 1 indigo, 1 orange, and 1 violet.
- This gives a total of 8 markers.

**Step 3: Plug in the values into the probability formula.**
- Number of desired outcomes = 1 (the blue marker)
- Total outcomes = 8 (the total number of markers)

Thus, the probability that Serenity will pick up the blue marker is:

\[
\text{Probability} = \frac{1}{8}
\]

So, you can fill in the blanks like this:

\[
\text{Number of desired outcomes} = 1 \quad \text{Total outcomes} = 8
\]

And the final probability is:

\[
\frac{1}{8}
\]
