5 0

<span>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 </span>

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
