what is the probability of getting a vowel (a success) for the spinner shown? 1/2 1/3 1/6

Explanation:

Step1: Identify total outcomes

The spinner has 3 equal - sized sections. So the total number of possible outcomes when spinning the spinner is 3.

Step2: Identify favorable outcomes

The vowels among the letters on the spinner are 'A'. So the number of favorable outcomes (getting a vowel) is 1.

Step3: Calculate probability

The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{1}{3}$.

Answer:

$\frac{1}{3}$
