a license plate has 2 letters followed by 4 digits.how many license plates are possible if the digits and letters can be repeated?
i think it is i am i correct thank you for helping me
about 21 letters
10 digits 0,1 ... 9
21*21 = 441
10^4 = 10,000
so I get
but these are the only answers and there is 26 letters in the alphabet
sorry, yes, 26
so 26 * 26
if the letters and numbers can be repeated, that is what I get
If they could not be repeated then
26*25 * 10*9*8*7 = 3,276,000
but these r the only choices
so what would it be
I can not make it come out to one of those choices.
the letters and numbers can be repeated, so it would be
there are 2 spaces for letters with 26 choices and 4 spaces for digits with 10 choices.
so, your answer is 6760000
