Discrete Mathematics includes topics like Factorial, Even, Odd, Circular Permutations, Combinations, Permutations, Permutations Replacement, Combinations Replacement, etc. We have covered all the formulas for the related concepts in the coming sections. They are as such
Factorial is a function that multiplies the number by every number below it and is denoted by the exclamation mark symbol. The formula for finding factorial is n!
Factorial = n! = n*(n-1)!
You can determine the Even Permutations for a given set of numbers easily. The formula for finding the Even Permutations of a given set is n!/2 for n> 2. You can simply substitute the value of n in the formula and then find the even permutation easily.
Even Permutations = n!/2 for n> 2
For a set of n elements, there exists n!/2 for n>=2 Odd Permutations. Substitute the value of n in the formula and perform required calculations to get the Odd Permutations effortlessly.
Odd Permutations = n!/2 for n>= 2
In general, Circular Permutations is nothing but arranging distinct objects around a fixed circle. Circular Permutation is given by the formula (n-1)!. Plugin the value of n given and solve to get the number of ways you can arrange distinct objects around a circle.
P(n) = (n-1)!
A combination is nothing but the number of ways in which you can select r elements out of a set containing n objects where order doesn’t matter and repetitions are not allowed. It might be difficult to write all the possible sets thus we have provided a simple formula to calculate the different combinations.
nCr = C(n,r) = n!/(r! (n-r)!) where n is the total number of elements in the set and r is the number of elements chosen from the set.
A permutation is a number of ways in which you can select r elements out of a set containing n distinct objects in which order matters. Make use of the formula below to calculate the Permutations in a matter of seconds.
P(n,r) = n!/(n-r)! for n ≥ r ≥ 0
where P is the number of permutations in the set, n is the total number of elements in the set and r is the total number of items you choose from the set.
This is the case of Combinations in which Repetitions are allowed. In fact, each time you pick an element you put it back to the set. The formula to calculate Combinations Replacement is given by
CR(n, r) or C'(n,r) = (r+n-1)!/(r! * (n-1)!)
Where C'(n,r)) is the number of combinations with repetition or replacement, n is the total number of elements in the set, and r is the number of elements you choose from this set.
In the case of Permutations Replacement, a sample of r elements is taken from a set of n distinct objects, order matters, and replacements are allowed.
Where p is the number of permutations, n is the total number of elements in the set, and r is the number of elements you choose from this set.
Example: Calculate Discrete Mathematics for n = 5, r = 2?
Given n= 5, r = 2
Formula for Factorial is n!
Place the value of n i.e. 5
Factorial = 5!
Even Permutations = n!/2 for n> 2
Placing the value of n= 5 we get
Odd Permutations = n!/2 for n>=2
Substitute the value of n we get the equation as under
Circular Permutations P(n) = (n-1)!
Formula for Combinations is nCr = C(n,r) = n!/(r! (n-r)!)
5C2 = 5!/(2!(5-2)!)
Formula for Permutations is P(n,r) = n!/(n-r)! for n ≥ r ≥ 0
Substitute the value of n, r i.e. 5 and 2 in the formula
P(5, 2) = 5!/(5-2)!
The formula for Combinations Replacement is C'(n,r) = (r+n-1)!/(r! * (n-1)!)
Placing the values of n, r i.e. 5 and 2 in the above formula we get
C'(5,2) = (2+5-1)!/(2!*(5-1)!)
The formula for Permutations Replacement is PR(n,r)=nr
PR(5, 2)= 52
