Answer:

The probability density function of <em>X</em> is:

f_{X}(x)=\frac{1}{15-5}=\frac{1}{10};\ 5

Step-by-step explanation:

A continuous Uniform distribution is the probability distribution of a random outcome of an experiment that lies with certain specific bounds.

Consider that random variable <em>X</em> follows a continuous Uniform distribution and the value of <em>X</em> lies between <em>a</em> and <em>b</em>.

The probability density function of the random variable <em>X</em> is:

f_{X}(x)=\frac{1}{b-a};\ a

Now, in this case it is provided that the amount of salad taken is uniformly distributed between 5 ounces and 15 ounces.

The random variable <em>X</em> is defined as:

<em>Χ</em> = Salad plate filling weight.

The probability density function of the salad plate filling weight is:

f_{X}(x)=\frac{1}{15-5}=\frac{1}{10};\ 5

Okay, we know the price of the child's ticket (x), which is 5.75 dollars less than the adult's ticket.
Let's say that the price of the adult's ticket is a. Since the child's ticket is 5.75 less that the adult's ticket, we can write it this way:
a = 5.75 + x
