To find the probability of the spinner landing on the red section, you need to compare the size of the red section to the size of the whole circle.
1.
Identify the total degrees in a circle: A full circle always has
360 degrees. This represents the total possible outcome (a probability of 1).
2.
Identify the degrees for the red section: The problem states that the central angle for the red section is
30 degrees.
3.
Set up the fraction: Probability is the favorable outcome over the total outcome.
$$P(\text{Red}) = \frac{\text{Degrees of Red}}{\text{Total Degrees}}$$
$$P(\text{Red}) = \frac{30}{360}$$
4.
Simplify the fraction: Both numbers can be divided by 30.
* $30 \div 30 = 1$
* $360 \div 30 = 12$
So, the probability is $\frac{1}{12}$.
Final Answer:
1/12
