Question

a spinner with 12 equally sized slices has 5 red slices, 3 blue slices, and 4 yellow slices. the dial is spun and stops on a slice at random. what is the probability that the dial stops on a red slice? write your answer as a fraction in simplest form.

Explanation:

Step1: Define total possible outcomes

Total slices = 12

Step2: Define favorable outcomes

Red slices = 5

Step3: Calculate probability

Probability = $\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}} = \frac{5}{12}$

Answer:

$\frac{5}{12}$
