## How many combinations of 4 items are there?

You multiply these choices together to get your result: 4 x 3 x 2 (x 1) = 24. Combinations and permutations are often confused by students – they are related, but they mean different things and can lead to totally different interpretations of situations and questions.

## How many numbers can be made using 3 digits?

There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6. 720 / 6 = 120.

## What is the formula for permutations?

The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n! (n−r)! A code have 4 digits in a specific order, the digits are between 0-9.

## How many combinations of 6 items are there?

With 1 item there are 6 possibilities with 2 you only have 5 choices after the first if you don’t repeat the same item. So for 6 items the equation is as follows 6*5*4*3*2= 720 possible combinations of 6 items.
