Here total number of ways to put C on first position =1 number of ways to put any letter on second position = 26 similarly for remaining positions. total number of ways = 1*26*26*26*10*10*10*10

first letter must be a C that is 1 choice, first slot is 1 choice 3 letter spaces left we ar allowed to repeat ther are 26 letters in the alphabet and 10 digits so there are 26 choices for each of the 3 letter slots and 10 choices for the last 2 slots so the number of licence plates is 1*26*26*26*10*10=1757600 different licecne plates
