what probabilities represent events that are unlikely to occur

Question

select all that apply
10/1 5.10 8/15 1/2 2/3 1/8 100/200 6/7 2/9

Answer 1

In probability, events that are considered unlikely to occur typically have probabilities less than 0.5 (or 50%). Let's convert the probabilities provided into decimal form to assess their likelihood:

1. 10/1 = 10.0 (unlikely)
2. 5.10 = 5.1 (unlikely)
3. 8/15 = 0.533 (not unlikely, more likely than not)
4. 1/2 = 0.5 (equally likely)
5. 2/3 = 0.667 (likely)
6. 1/8 = 0.125 (unlikely)
7. 100/200 = 0.5 (equally likely)
8. 6/7 = 0.857 (likely)
9. 2/9 = 0.222 (unlikely)

Based on this evaluation, the events that represent probabilities that are unlikely to occur (less than 0.5) are:

• 10/1
• 5.10
• 1/8
• 2/9

So, select 10/1, 5.10, 1/8, and 2/9 as the events that are unlikely to occur.
