Teaching Transcript

🎙️

What is the chance of spinning either a prime number or a perfect square in one spin of this spinner?

We know that probability is desired outcomes, divided by total outcomes.

In this case there are 2 primes and one square, for a total of 3 ways to get a desired outcome. There are 6 total outcomes for the spinner

3 over 6 simplifies to a probability of 1 over 2

If we want, we can also express this as 0.5 or 50 percent.
