Answer

Explanation:

Step1: Identify total and favorable outcomes

Total slices = 12, yellow slices = 4

Step2: Calculate probability

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{4}{12}$

Step3: Simplify the fraction

$\frac{4\div4}{12\div4}=\frac{1}{3}$

Answer:

$\frac{1}{3}$
