Math Problem Statement

The lifetime, in years, of some electronic component is a continuous random variable with the density

f(x) =

Find

a)      The value of k, as f(x) is valid density function.

b)       the cumulative distribution function,

c)       the probability for the lifetime to exceed 2 years.

Solution

To help you with the questions, we need to assume that you are dealing with a valid probability density function (pdf) that is defined as f(x)f(x). However, the exact form of f(x)f(x) is missing in your query. A typical pdf is often given in a piecewise format, for example:

\begin{cases} k \cdot g(x) & \text{for } x \in [0, \infty) \\ 0 & \text{otherwise} \end{cases}$$ where $$k$$ is a constant and $$g(x)$$ is some function defining the pdf. In order to proceed, I'll need the specific form of $$f(x)$$ to give accurate solutions. Could you please provide the functional form of $$f(x)$$? Once I have that, I can: - Find the value of $$k$$ using the property that the total probability must sum to 1. - Compute the cumulative distribution function (CDF). - Calculate the probability that the lifetime exceeds 2 years.
