What is the appropriate K valuefor this to be a legitimate probability density function?

Im not exactly sure of the approach to this problem...

Well all you need to do is to understand it means for some function to be considered a legitimate pdf. What criteria must it satisfy?

I would first explain that a probability density function (PDF) is a mathematical function that describes the probability of a random variable falling within a certain range of values. It is often used in statistics and probability theory to model random phenomena.

In order for a function to be a legitimate PDF, it must meet certain criteria. First, the function must always be non-negative, meaning that the output of the function can never be negative. Second, the total area under the curve of the function must equal 1, as the total probability of all possible outcomes must equal 1.

To determine the appropriate K value for this specific PDF, we would need to know the context or the problem it is being used for. Without further information, it is difficult to determine the appropriate K value. However, we can assume that the K value would need to be chosen in a way that satisfies the criteria of a legitimate PDF, meaning it must be greater than 0 and result in a total area under the curve equal to 1.

In order to solve this problem, we would need to know the specific context and purpose of the PDF, as well as any other relevant information. Without this information, it is not possible to determine the appropriate K value. However, as a general approach, the K value should be chosen in a way that satisfies the criteria of a legitimate PDF and is relevant to the problem at hand.
