Question

the table below shows the favorite movie theater snack for adults and children. | | popcorn | candy | hot dogs | total | |---|---|---|---|---| | adults | 20 | 2 | 3 | 25 | | children | 15 | 8 | 2 | 25 | | total | 35 | 10 | 5 | 50 | of the adults surveyed, what is the conditional relative frequency for those who like to eat popcorn? 4/5 3/5 2/5 4/7

Explanation:

Step1: Recall conditional - relative - frequency formula

Conditional relative frequency of a category within a subgroup is $\frac{\text{Frequency of the category in subgroup}}{\text{Total frequency of the subgroup}}$.

Step2: Identify relevant frequencies

The number of adults who like popcorn is 20, and the total number of adults surveyed is 25.

Step3: Calculate the conditional relative frequency

The conditional relative frequency of adults who like popcorn is $\frac{20}{25}=\frac{4}{5}$.

Answer:

A. 4/5
