Question

A spinner with 8 equal-sized sections is used for a game. Based on the descriptions below, is the spinner fair? Explain. The probability the pointer will land on yellow is 1 out of 4. The probability the pointer will land on blue is 2 out of 8. The probabilities that the pointer will land on green or red are both 25%.

Answer 1

It is fair because if you simplify 2/8 it is 1 out of 4. And 25% is equal to 1 out of 4 (like how it takes 4 quarters to make a dollar)
