1. **State the problem:** We toss two six-sided dice.
Event A: The first die lands on 1 or 2.
Event B: The second die lands on 5.
We want to find the probability that both events occur simultaneously.
2. **Recall the formula for independent events:**
$$P(A \text{ and } B) = P(A) \times P(B)$$
This applies because the outcome of the first die does not affect the second die.
3. **Calculate each probability:**
- For Event A, the first die can be 1 or 2, so there are 2 favorable outcomes out of 6.
$$P(A) = \frac{2}{6}$$
- For Event B, the second die must be 5, so 1 favorable outcome out of 6.
$$P(B) = \frac{1}{6}$$
4. **Calculate the combined probability:**
$$P(A \text{ and } B) = \frac{2}{6} \times \frac{1}{6} = \frac{2}{36}$$
5. **Simplify the fraction:**
$$\frac{2}{36} = \frac{\cancel{2}^1}{\cancel{36}^ {18}} = \frac{1}{18}$$
**Final answer:**
$$P(A \text{ and } B) = \frac{1}{18}$$
