The problem in the image reads:

**"Pamela's computer printer allows for optional settings with a panel of four on-off switches in a row. How many different settings can she select if there are no restrictions on the switches?"**

This is a classic problem of counting possible combinations of binary (on/off) switches. 

Each of the four switches has two possible states: ON or OFF. Since there are no restrictions on the switches, each switch can be independently set to either ON or OFF. 

The total number of different settings is given by multiplying the number of possibilities for each switch. For \( n \) switches, each having 2 possible states, the total number of combinations is:

\[
2^n
\]

For \( n = 4 \) switches, the calculation is:

\[
2^4 = 16
\]

So, Pamela can select **16 different settings**.

Here are some related questions:
1. What if Pamela had 5 switches? How many different settings could she select?
2. How many combinations can be made if there were restrictions on some of the switches (e.g., 2 switches must always be ON)?
3. What is the general formula for counting combinations of switches for any \( n \)?
4. How many settings can be made if one of the switches is faulty and can no longer toggle?
5. What happens if there were more than two states for each switch (e.g., 3 possible settings per switch)?

**Tip**: Problems with binary choices often lead to powers of 2 in their solutions—each binary option doubles the number of possibilities.
