Question

The table shows the results for spinning the spinner 80 times. What is therelative frequency for the event "spin a 4"?21414Experiment TableOutcome 1 2 3 4 Number ofTrials18 30 12 20 80FrequencyThe relative frequency for the event "spin a 4" is

Answer 1

Relative frequency is the ratio of the number of times or frequency of an outcome to the total number of outcomes.

From the information given,

Total number of times of spinning a 4 = 20

Total number of spins = 80

Thus,

The relative frequency of the event 'spin a 4' = 20/80 = 1/4
