Question

a car dealer organizes the inventory of a specific model of car into a frequency table comparing the type of car and the model year. the dealer used the data from the frequency table to create this conditional relative frequency table by column.
car inventory

	coupe	sedan	total
previous model year	0.1	0.25	~0.21
total	1.0	1.0	1.0

which is the best description of the 0.1 in the table?
given that a car is a coupe, there is a 10% chance it is from the previous model year.
given that a car is from the previous model year, there is a 10% chance that it is a coupe.
there is a 10% chance that the car is from the previous model year.
there is a 10% chance that the car is a coupe.

Explanation:

This is a conditional relative - frequency table by column. The columns represent the type of car (Coupe and Sedan). The 0.1 is in the "Coupe" column and "Previous Model Year" row. Conditional relative - frequency by column gives the proportion within each column. So, given that a car is a coupe, the value 0.1 represents the proportion of coupes that are from the previous model year.

Answer:

Given that a car is a coupe, there is a 10% chance it is from the previous model year.
