would this answer be 80?

If you spin the spinner 80 times, what is the best possible prediction for the number of times it will land on an 8?

1 answer

To make a prediction about how many times the spinner will land on an 8 after spinning it 80 times, you would need to know the probability of the spinner landing on an 8.

If the spinner is fair and has 10 equal sections labeled 0 through 9, the probability of landing on each number, including 8, is \( \frac{1}{10} \) or 0.1.

Using that probability, you can predict the number of times it will land on an 8 by multiplying the total number of spins (80) by the probability of landing on an 8:

\[ 80 \times \frac{1}{10} = 8 \]

So, the best possible prediction for the number of times it will land on an 8 after spinning the spinner 80 times is 8, not 80.
