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

sukhopar [10]

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
