# How many ways can 4 cards be selected from a 52 card deck?

## How many ways can 4 cards be selected from a 52 card deck?

SOLUTION: For hands of cards, unless we are told otherwise, the cards dealt must be different, and the order in which they are dealt does not matter. So, we are counting the number of combinations of 4 cards chosen from 52, which gives 52C4=52P4 / 4! =(52Χ51Χ50Χ49) / (4Χ3Χ2Χ1) =6,497,400 / 24 = 270,725 hands.

How many ways can 4 cards from a deck of cards can be arranged?

If you’ve got four cards you can arrange them in 4! = 24 ways.

What is the probability of drawing 4 aces in a row from a standard deck of cards?

4/52
The chance of drawing one of the four aces from a standard deck of 52 cards is 4/52; but the chance of drawing a second ace is only 3/51, because after we drew the first ace, there were only three aces among the remaining 51 cards. Thus, the chance of drawing an ace on each of two draws is 4/52 × 3/51, or 1/221.

### What’s the difference between permutations and combinations?

What Is the Difference Between Permutation and Combination? The permutation is the number of different arrangement which can be made by picking r number of things from the available n things. The combination is the number of different groups of r objects each, which can be formed from the available n objects.

How many different 4 card hands are possible?

270,725 different
Wow, this means there are 270,725 different 4 card hands.

How many combinations are in a 52 card deck?

If you were to shuffle a deck of 52 cards and lay them out the possible order combinations are practically endless. The total number of combinations is a factorial of 52, or 52!, which translates to 8.06e+67, a number that means absolutely nothing to me.

## How many ways can a 52 card deck be arranged?

In our simple example, the number of ways four people can be arranged into chairs is written as four factorial, which equals 24. So let’s go back to our deck. Just as there were four factorial ways of arranging four people, there are 52 factorial ways of arranging 52 cards.

What is the probability of drawing four aces in poker from a 52 card deck?

### How do you know when to use permutation or combination?

Permutations are for lists (order matters) and combinations are for groups (order doesn’t matter). You know, a “combination lock” should really be called a “permutation lock”. The order you put the numbers in matters. A true “combination lock” would accept both 10-17-23 and 23-17-10 as correct.

How can you determine if you need to use a combination or permutation to count the number of outcomes?

If the order doesn’t matter then we have a combination, if the order do matter then we have a permutation. One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n!
