I see that you've uploaded an image. Let me process it and extract the mathematical content to assist you with solving the problem.From the image, I can see that there is a table and a question related to finding a probability or a specific value, followed by multiple-choice options.

Here’s the breakdown:

• There is a table with multiple columns and rows, possibly representing a distribution of some values.
• The question seems to ask for the value of $\sum x \cdot f(x)$, which typically suggests you're being asked to calculate the expected value $E(X)$ for a probability distribution. Here, $x$ represents a random variable and $f(x)$ is likely its corresponding frequency or probability.

Could you clarify if this is a probability distribution problem where you need to compute the expected value (or something similar)? If so, I can guide you through the necessary steps.

Let me know if you'd like me to continue solving based on that assumption or if there's anything more specific I should know!
