I thought to use combinations but it's still a very large number.I have been given a hint that the answer is not smaller than 1000 and not bigger than 7000. With my way I would get waaaay bigger numbers... Where am I going wrong?? View attachment 32308
You're assuming that the numbers can't be repeated. Where does it say that?I thought to use combinations but it's still a very large number.

If they were to repeat the possibilities would be even bigger.You're assuming that the numbers can't be repeated. Where does it say that?
Yes. I divided 18 by 6 and came up with 1. Maybe I should stop posting today. I seem to be making arithmetic mistakes all over.
Sitting in the corner for a spell does wonders when it comes to not making silly arithmetic mistakes.Yes. I divided 18 by 6 and came up with 1. Maybe I should stop posting today. I seem to be making arithmetic mistakes all over.
smaller than 1000 and not bigger than 7000 equates to smaller than 1000--for the record.I have been given a hint that the answer is not smaller than 1000 and not bigger than 7000. With my way I would get waaaay bigger numbers... Where am I going wrong?? View attachment 32308
But the OP is, "the answer is not smaller than 1000 and not bigger than 7000". Therefore if "w" is the number of ways then 1000 ≤ w ≤ 7000smaller than 1000 and not bigger than 7000 equates to smaller than 1000--for the record.
The problem clearly states that three numbers are to be chosen. If a number is repeated the would not be three.You're assuming that the numbers can't be repeated. Where does it say that?
I knew my corner time was coming up soon. You got me good.But the OP is, "the answer is not smaller than 1000 and not bigger than 7000". Therefore if "w" is the number of ways then 1000 ≤ w ≤ 7000
In programming I avoid boolean variable names that begin with the prefix "not" since this often causes me a lot of confusion For example:-
boolean not_Steven_is_in_the_corner = false;
