Problem-Solving and Data Analysis practice question
A spinner has 8 equal sections numbered 1 through 8. What is the probability that a single spin lands on a number greater than 5?
- A. 3/8Correct
- B. 5/8
- C. 1/2
- D. 3/5
Answer: A. 3/8
The numbers greater than 5 are 6, 7 and 8 — three of the eight equally likely sections. Probability = 3/8.
Why the other answers are wrong
- B. 5/8
- 5/8 is the probability of landing on 5 or LESS (1 through 5). 'Greater than 5' excludes 5 itself.
- C. 1/2
- 1/2 would be 4 favourable sections. There are only three numbers above 5 on a 1–8 spinner.
- D. 3/5
- 3/5 puts 5 in the denominator, but there are 8 equally likely sections in total.
