Question

a spinner with 10 equally sized slices has 3 blue slices and 7 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: Identify total and favorable outcomes

The total number of slices is 10. There are 0 red slices.

Step2: Use probability formula

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, the number of favorable outcomes (red slices) is 0 and total number of outcomes is 10. So $P=\frac{0}{10}$.

Answer:

$\frac{0}{10} = 0$
