If this spinner is spun once, what is the probability of getting a vowel? Give your answer as a fraction in its simplest form.

So exactly which letter are vowels? The vowel letters are A, E, I, O, U, and sometimes Y. So the spinner has an A. It has an E. It has an I. It does not have O. It does not have U. And it does not have Y.

So there are three vowels on the spinner. And we need to put three out of the total letters possible to land on. So let’s keep counting. There’s already three, four, five, six, seven, eight. So there are eight total letters on the spinner.

So the probability of getting a vowel from the spinner will be three out of the total eight. So does this reduce? Is there a number that goes into three and eight? There isn’t. So our final answer is three eighths.
