Percentages

Question

If you spin a spinner 400 times, about how many times will the spinner land on a number less than 4. Will it land on a number less than 4 exactly this number of times or about this number of times.

Answer 1

Incomplete information:  You need to say how many 'sectors' there are upon which the spinner can land (assuming that all sectors are congruent, i.e. their central angles are all the same number of degrees).

 

THEN you can compute the probability of the spinner landing "on 4"--such number will be theoretical, and will merely predict the approximate (most likely) ratio of such outcomes compared to all others. Theoretical probability does not guarantee the result of each experiment in spinning, however.
