. Now choose the first car. The no.of way of choosing the first car is equalled to 8 and imagine the first car Colour is black. Now we have a black car so we have to choose from 6 options apart from black.
Now no.of way of choosing the 2 car = 6 and imagine it is blue. Now we have to choose two colour car, so now we have 4 options to choose from. The no.of choosing the car = 4. Now let's calculate the total arrangement -
