How many three digit numbers have only even digits?
It's all about choice :) Do you consider 0 an even digit?
ummm..i guess yhu can
It's just multiplying the number of choices you have with each other... Ok, how many choices do you have for the first (hundreds) digit?
Knowing that there are 5 even digits {0,2,4,6,8}
idk..lol :) i dnt like these problems..im, confused
Ok, while it might seem like you have five choices for your first digit, you actually only have four. :P That's because 0 cannot be your first digit, otherwise, you get a two-digit number. So you have 4 choices for your first digit, how about the second?
half of them
what you mean half
i was wrong, i thought it said "even"
you have a three digit number and you want only even digits in the entire number right? like \(264\) use the counting principle
4 possibility for the first digit \(\{2,4,6,8\}\) then for the second digit you have possibilities since you can also have zero, and for third digit you have also 5 choices multiply the number of choices together
so the answer is 264
