Question

What is the conditional relative frequency of selling an item marked 50% off, provided the item sold is item 2?

Answer 1

Answer:

Conditional relative frequency = 0.67

Step-by-step explanation:

               50% off        Buy 1, get 1 free      Total

Item 1         12                       8                      20

Item 2         20                      10                     30

Total           32                      18                     50

Condition relative frequency table:

               50% off        Buy 1, get 1 free      Total

Item 1         $\frac{12}{20}=0.6$             $\frac{8}{20}=0.4$            $\frac{20}{20}=1$

Item 2        $\frac{20}{30}=0.67$           $\frac{10}{30}=0.33$          $\frac{30}{30}=1$

Total            $\frac{32}{50}=0.64$           $\frac{18}{50}=0.36$          $\frac{50}{50}=1$

Therefore, conditional relative frequency of selling an item marked 50% off, provided the item sold is item 2 = 0.67
