What are probability combinations?
Combinations in probability theory and other areas of mathematics refer to a sequence of outcomes where the order does not matter. For example, when you’re ordering a pizza, it doesn’t matter whether you order it with ham, mushrooms, and olives or olives, mushrooms, and ham.
How many combinations of 4 items are there?
I.e. there are 4 objects, so the total number of possible combinations that they can be arranged in is 4! = 4 x 3 x 2 x 1 = 24.
How do you solve a combination example?
A few examples
- Combination: Picking a team of 3 people from a group of 10. C ( 10 , 3 ) = 10 ! / ( 7 ! ∗ 3 ! ) = 10 ∗ 9 ∗ 8 / ( 3 ∗ 2 ∗ 1 ) = 120 .
- Combination: Choosing 3 desserts from a menu of 10. C(10,3) = 120. Permutation: Listing your 3 favorite desserts, in order, from a menu of 10. P(10,3) = 720.
How many combinations of 8 items are there?
40,320 different combinations
Note: 8 items have a total of 40,320 different combinations. For the sake of output and server capacity, we cannot let you enter more than 8 items!
What is combinations combinations with repetition explain with example?

What is the example of combination?
A few examples Combination: Picking a team of 3 people from a group of 10. C ( 10 , 3 ) = 10 ! / ( 7 ! ∗ 3 ! ) = 10 ∗ 9 ∗ 8 / ( 3 ∗ 2 ∗ 1 ) = 120 .
How many combinations of 3 numbers are possible?
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.
How many ways can you arrange 4 things?
24 different ways
(Another example: 4 things can be placed in 4! = 4 × 3 × 2 × 1 = 24 different ways, try it for yourself!)
How many combinations of 3 options are there?
3*3*3=27 unique possibilities.
