To find the mean of the given probability distribution, we use the formula for the mean (expected value):

\[
\mu = \sum (x \cdot P(x))
\]

### Step-by-Step Solution:


Find the mean of this probability distribution: x = {0, 1, 2, 3} with P(x) = {0.25, 0.3, 0.25, 0.2}. Round your answer to one decimal place.
