![**Finding the Expected Value of a Random Variable**
**Problem Statement:**
Find the expected value for the random variable whose probability function graph is displayed here.
**Graph Explanation:**
- The graph is a bar chart representing the probability function of a discrete random variable.
- The x-axis (labeled 'x') represents the values of the random variable, ranging from 0 to 5.
- The y-axis (labeled 'P') represents the probability of each value, ranging from 0 to 0.5.
- The bar heights represent the probabilities of the random variable taking on each corresponding value.
- Probability at x = 1: 0.2
- Probability at x = 2: 0.1
- Probability at x = 3: 0.15
- Probability at x = 4: 0.05
- Probability at x = 5: 0.5
**Question:**
What is the expected value of the random variable?
*(Type an integer or a decimal.)*
