Question

The spinner shown has 7 congruent sections.%0D%0A%0D%0A%0D%0AThe spinner is spun 210 times. What is a reasonable prediction for the number of times the spinner will land on an odd number?

Answer 1

Since there are only 7 sections on the spinner, each odd number (1, 3, 5, 7) has an equal chance of being landed on. Therefore, the expected number of times the spinner will land on an odd number is 3 out of 7 spins.

To predict the number of times the spinner will land on an odd number after 210 spins, we can calculate:

(3/7) * 210 = 90

Therefore, a reasonable prediction is that the spinner will land on an odd number approximately 90 times out of 210 spins.
