Question

A man went to his room and in his closet for his stash of treasures.
On the lock there are three rotational rows of numbers from 0-9
Unfortunately, the man couldn't remember what it was. How many combinations can he use to get the lock open?

Do you dare?

Answer 1

there is only one combination he can use to open..

Answer 2

Altogether, there are 2,000 Possible Combinations!
Explenation: 0 1 2 3 4 5 6 7 8 & 9 are all ten Arabic numerals. The doubled numerals is 0 0 0 - 9 9 9 & then the next step would be if the first numeral. Then which direction to start with; go clockwise, counterclockwise & clockwise. Or Counterclockwise, clockwise & counterclockwise!

Answer 3

let's see 9 digits, 9 choices for each of the 3 spaces. i think it goes something like this: 9!/3!(6!) so that simplifies to 362880/4320 which is 84, so if i did it right, there are 84 different possibilities. I may be wrong, but if i remember correctly, thats how you solve those type of problems.

Answer 4

1000

Answer 5

how many combinations can he use to get the lock open? just one, if it's a regular lock.

how many possible combinations are there? that's a different question.

Answer 6

its 10X10X10
since there are 10 different numbers, thats were u get the 10 from, and there are three numbers to a combination, so u multiple it three times.

Answer 7

How many combinations can he use to get the lock OPEN? Only one...the correct one.
There are 1,000 different combinations he can try, of course.

Answer 8

999 - sorry 1000 the person above is correct.
You can have 000, then 001, then 002, then 003 etc.. right up to 999.

So it is 999 plus the 000 to start with = 1000

Answer 9

999 because the lock would be in certain combination when he found it, so there would be 999 other possibilities!

Answer 10

27 combinations.
