A spinner is divided into 8 equal sections, numbered 1 through 8. What is the probability of spinning a number greater than 5?
1/8
1/4
3/8
5/8
คำอธิบาย
Numbers greater than 5 are 6, 7, and 8. 3 favorable outcomes divided by 8 total outcomes means the probability = 3/8. However this option is unavailable, so 6,7,8 is 3/8. 6 and 7 is 2/8 = 1/4
