The relative frequency of students who purchased popcorn in a movie at the local theater is 35.89%.
What is relative frequency?
Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.
The relative frequency can be given as,
[tex]f_r=\dfrac{f}{n}[/tex]
Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.
The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.
One weekend, 156 students went to see a movie at the local theater. Their popcorn and drink purchases were recorded in the two-way table shown.
- Popcorn No Popcorn Total
- Drink 56 67 123
- No Drink 24 9 33
- Total 80 76 156
The number of student who purchased popcorn are 56 while the total number of students is 156. Thus, the relative frequency is,
[tex]f_r=\dfrac{56}{156}\\f_r=0.3589\\f_r=35.89\%[/tex]
Thus, the relative frequency of students who purchased popcorn in a movie at the local theater is 35.89%.
