Question 778846
Answer 474924 by Edwin McCravy(9326) is not correct!! 
because, the question stated: The three digits numbers MUST be even 

for part (a)

Letters:
26*25*26 = 15600 = Permutation(26,3)

Numbers:
5*4*3 = 60 = Permutation(5,2)

Final answer is = 15600*60 = 936 000 different license plates are possible (by multiplicative rule of counting)

Part (b): the only change will be in the numbers 
4*3*2 = 24

final answer is = 15600*24 = 3744 00 different license plates are possible
