Count Sections on Spinner: Count the total number of sections on the spinner.
Count Sections $1$ or $2$ : Count how many of those sections are labeled as $1$ or $2$ .
Use Probability Formula: Use the probability formula: $P(\text{event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$ .
Calculate Probability: Calculate the probability: $P(1 \text{ or } 2) = \frac{\text{Number of sections with } 1 \text{ or } 2}{\text{Total number of sections}}$ .
$3$ Sections with $1$ or $2$ : There are $3$ sections with $1$ or $2$ and $5$ total sections.
Calculate $P(1 \text{ or } 2)$ : So, $P(1 \text{ or } 2) = \frac{3}{5}$ .
