- (a) Explain why the function

is a probability density function.

- (b) Find
*P*(*X*< 4). - (c) Calculate the mean. Is the value what you would expect?

(a)

To determine

**To explain:** the given function as probability density function with explanation.

Explanation

**Given information:**

The given function is

**Calculation:**

Show the function as follows:

Show the conditions of probability density function as follows:

(A) The probability density function *f* of a random variable *X* satisfies the condition
*x*.

(B) The probabilities are measured on a scale from 0 to 1, it follows that

Apply the probability density function (B) in Equation (1) as shown below

(b)

To determine

**To calculate:** The value of

(c)

To determine

**To calculate:** The value of mean
