A car is available in seven different exterior colors and six different interior colors. how many unique color combinations are possible?
Why the OA is correct, what am I missing? My answer choice is (D)
There are 7 different ways to choose an exterior color and 6 different ways to choose an interior color.
So the number of combinations is 7 * 6 = 42.
(Imagine A B C D E F G are the choices for exterior colors and H I J K L M are the choices for interior colors.
If you choose A as the exterior color you can choose any of H I J K L M as interior color. So 6 combinations when you choose A as exterior.
If you choose B as the exterior color you can choose any of H I J K L M as interior color. So 6 combinations when you choose B as exterior.
So you can see that for each exterior color there is an option of 6 interior colors. So total possible combinations = 7*6 = 42 )
Please recheck the OA.
Answer should be B
