How many automobile license plates can be made if each plate contains two different letters followed by three different digits?

 

Answers (1)

Each plate contains 2 different letters followed by 3 different digits  

Arrangement of 26 letters taken 2 at a time = ^{26}P_2=26*25=650 

Arrangement of 10 digits taken 3 at a time = ^{10}P_3=10*9*8=720

The total number of license plates = 650*720=468000
