How many license plates are possible consisting of 4 letters followed by 3 digits, if the first letter must be a C?
this question is permutation
36 lincence plates
you have 1 choice for the first letter
can letters and digits repeat
apart from the the begining letter "C" D,E,F can go around themselves 6 times and the same to the numbers too. 3 numbers can rotate 6 times which in total gives u 36 plates all starting with letter C
are u clear with the answer
@ibarfi I got 1*26*26*26 *10*10*10
i sent u a msg explaining the answe
maybe it means with the first 4 letters then?
or the letters CDEF only?
otherwise perls answer is right,26^3*10^3
unless u want to use all numbers from 1 to 10 all letters from A to Z..... if so u got the right answer but if it is restricted to only specific letters and numbers my answer is correct
