Based on the information provided about the 8-sided fair spinner and the probabilities shown on the scale, here is how to determine the probability of spinning a 4:
1) The spinner has 8 sides total, labeled 1, 1, 3, 3, 4, 5, 5, 5. This means it has 2 sides labeled 1, 2 sides labeled 3, 1 side labeled 4, and 3 sides labeled 5.
2) For the probability scale, the arrow options are:
- 0.125 (1 in 8 probability)
- 0.25 (1 in 4 probability)
- 0.5 (1 in 2 probability)
- 0.75 (3 in 4 probability)
- 1 (certainty)
3) Since the spinner has only 1 side labeled 4, the probability of spinning a 4 is 1 out of the 8 sides.
4) Therefore, the correct arrow showing a probability of 0.125 or 1 in 8 chance of spinning a 4.
In summary:
Spinner has 8 sides: 2 (1's), 2 (3's), 1 (4), 3 (5's)
1 side is labeled 4
Probability of landing on 4 is 1 in 8
Arrow showing 0.125 or 1 in 8 chance is correct
Does this make sense? Let me know if any part of the explanation is unclear. I can provide another example or visual diagram if needed to better illustrate determining probabilities from information about a spinner or other probability scenario.
The key concepts are:
1) Identifying the probabilities shown on the scale (options and values)
2) Counting the number of successes (4's) and total possible outcomes (8 sides)
3) Calculating the probability by (number of successes) / (total possible outcomes)
4) Choosing the arrow/scale option that matches the calculated probability
Please feel free to ask any follow up questions. I'm happy to provide more examples or explain probabilities and probability calculations in another way.
Let me know if you have any other questions!
