How many license plates can be made which have the form ###LL? Answer 1,757,600 175,600 676,000 2,947,000
Are the characters on the plate always letters or can there be numbers and letters. 324LL, 3HTLL --> Are those acceptable and can digits be repeated? Could the tag read LLLLL ?
Check the problem instructions.
yes
So, numbers and letters with repeats allowed?
There are 26 letters in this alphabet. There are 9 digits.
26 + 9 = 35 total of numbers and letters. Tags possible using Fundamental Principle of Counting: 35*35*35*1*1 where the two ones represent the number of ways to select the Ls.
That includes a tag with the digits 000LL
isnt there a possibility of 10 digits
0, 1, 2, 3 ,4 5, 6, 7, 8, 9 Yes.
this is all my instructions say So the general form is: three letters, followed by four numbers. Or we could describe these as: LLL#### where L stands for "some letter (from the alphabet)," and # stands for "some number (some digit 0, 1, 2, … , 8, 9)."
Okay, with no instructions, I read L as the actual letter L. So, hold on.
# = 10 L = 26 10 * 10 * 10* 26 * 26 =
676,000
correct
