Answer:

The expected value of the distribution is 7.

Step-by-step explanation:

The random variable X is known to be uniformly distributed between 2 and 12.

The probability density function of X is:

[tex]f_{X}(x)=\frac{1}{b-a};\ a<X<b[/tex]

Here a = 2 and b and 12.

Compute the expected value of the distribution as follows:

[tex]E(X)=\frac{a+b}{2}[/tex]

         [tex]=\frac{2+12}{2}\\\\=\frac{14}{2}\\\\=7[/tex]

Thus, the expected value of the distribution is 7.
