## Explanation

### Probability Calculation

The probability of an event occurring can be calculated using the formula:

$P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$### Finding Favorable Outcomes

In this scenario, the spinner is divided into 4 equal parts, each labeled 1, 2, 3, and 4. The favorable outcome here is landing on the number 2. Therefore, we have the following:

**Number of favorable outcomes**: 1 (since there's only one sector labeled 2)**Total number of possible outcomes**: 4 (since there are 4 equal parts)

### Calculating the Probability

To find the probability of the spinner landing on 2, we apply the values into the formula:

$P(\text{landing on 2}) = \frac{1}{4}$ $P(\text{landing on 2}) = 0.25$Where:

$\begin{aligned} & \text{Number of favorable outcomes} = 1 \\ & \text{Total number of possible outcomes} = 4 \end{aligned}$Thus, the probability of the spinner landing on 2 is **0.25** or **25%**.
