I have a question on probability

**Probability and Statistics: Class Attendance Survey**

This exercise involves analyzing survey data from college students about the number of weekdays they attend live classes on campus.

### Survey Data

| Number of Days in Class (x) | Probability P(x) |
|-----------------------------|------------------|
| 0                           | 0.30             |
| 1                           | 0.12             |
| 2                           | 0.32             |
| 3                           | 0.10             |
| 4                           | 0.12             |
| 5                           | 0.04             |

### Questions

1. **Probability of Attending at Least 3 Days a Week:**
   - To find this probability, add the probabilities of attending 3, 4, and 5 days:
     \[
     P(x \geq 3) = P(3) + P(4) + P(5) = 0.10 + 0.12 + 0.04
     \]

2. **Probability of Attending Less Than 3 Days a Week:**
   - To find this probability, add the probabilities of attending 0, 1, and 2 days:
     \[
     P(x < 3) = P(0) + P(1) + P(2) = 0.30 + 0.12 + 0.32
     \]

### Instructions

- Click "Submit" to complete the assessment once you have calculated the probabilities.
