**1. Total Outcomes**
* Each student can have two possible outcomes:
* S: Suffers from math anxiety
* N: Does not suffer from math anxiety
* For two students, the total number of possible outcomes is 2 * 2 = 4.
**a. Tree Diagram**
```
Start
/ \
S N
/ \ / \
S N S N
```
* The tree diagram visually represents the possible outcomes for each student and their combinations.
**b. Venn Diagram**
* Create two overlapping circles.
* One circle represents the first student, the other represents the second student.
* Within each circle, divide it into two sections: S (suffers) and N (does not suffer).
* The overlapping region represents the outcome where both students suffer from math anxiety.
**c. List of Outcomes**
* **i. Both students suffer from math anxiety:** {SS} (Simple event)
* **ii. Exactly one student suffers from math anxiety:** {SN, NS} (Compound event)
* **iii. The first student does not suffer and the second suffers from math anxiety:** {NS} (Simple event)
* **iv. None of the students suffers from math anxiety:** {NN} (Simple event)
**Note:**
* **Simple Event:** An event that consists of a single outcome.
* **Compound Event:** An event that consists of two or more simple events.
