you pick a number between 20 and 50. what are the favorable outcomes for the event of picking a number that is divisible by 8?

List out the multiples of 8

8, 16, 24, 32, 40, 48, 56, 64, 72, 80

I'm going to highlight in bold the values between 20 and 50

8, 16, 24, 32, 40, 48, 56, 64, 72, 80

So the favorable outcomes, aka the outcomes we want, are: {24, 32, 40, 48}

These four values are all divisible by 8. Also, these values are between 20 and 50.
