The correct Answer is:
To solve the problem, we need to understand the relationship between the probabilities of the original values \( x_i \) and their corresponding transformed values \( f(x_i) \). ### Step-by-Step Solution: 1. **Understanding the Given Information**: We are given that the probability of getting \( x_i \) is \( p_i \). This means for each value \( x_i \) in our distribution, there is a corresponding probability \( p_i \). **Hint**: Identify what \( p_i \) represents in the context of the distribution. 2. **Replacing \( x_i \) with \( f(x_i) \)**: The question states that each \( x \) is replaced by its corresponding value \( f(x) \). Thus, we need to consider the new values \( f(x_i) \) instead of \( x_i \). **Hint**: Think about how the transformation \( f(x) \) affects the values but not the probabilities. 3. **Analyzing the Probability of \( f(x_i) \)**: When we replace \( x_i \) with \( f(x_i) \), we need to determine the probability of obtaining \( f(x_i) \). However, the transformation does not change the underlying favorable cases. The number of favorable outcomes for \( f(x_i) \) remains the same as that for \( x_i \). **Hint**: Consider the nature of probability and how it is defined in terms of favorable outcomes. 4. **Conclusion**: Since the favorable cases remain unchanged, the probability of getting \( f(x_i) \) is still \( p_i \). Therefore, we conclude that: \[ P(f(x_i)) = p_i \] **Hint**: Reflect on the principle that the probabilities associated with outcomes do not change when we apply a function to the outcomes. ### Final Answer: The probability of getting \( f(x) \) when the probability of getting \( x_i \) is \( p_i \) is \( p_i \).
