![**Probability Distribution of Daily Coffee Breaks of Coffee Drinkers**
The table below shows the probability distribution for \( X \), the number of daily coffee breaks taken per day by coffee drinkers. The objective is to determine the expected number of daily coffee breaks taken per day by coffee drinkers.
| \( x \) | \( f(x) \) |
|--------|------------|
| 0 | 0.40 |
| 1 | 0.20 |
| 2 | 0.15 |
| 3 | 0.10 |
| 4 | 0.08 |
| 5 | 0.07 |
To calculate the expected number of daily coffee breaks, you can use the formula for the expected value \( E(X) \):
\[ E(X) = \sum (x \cdot f(x)) \]
Given the choices:
- 2.50
- 2.35
- 3.79
- 1.47
- 1.36
Complete the calculation to identify the correct expected value from the provided options.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F49b6872f-8540-4d67-8f44-b13749eac041%2F46fda7e0-f30f-40ce-b9cf-7617d68249be%2F5dootm_processed.jpeg&w=3840&q=75)
