7 0

Answer:

3.5

Step-by-step explanation:

Let X be our random variable in the interval [0,7]

We notice that this is a continuous random variable of uniform distribution.

The mean of expected value of a uniform random variable X is:

$E(X)=\frac{(a+b)}{2}\\\\=\frac{(7+0)}{2}\\\\\\=3.5$

Hence, the mean of the distribution is 3.5
