Factorial Calculator, \[\mathrm{n}!\]

Answer

Factorial of a number \[n\] is defined as the product of all whole numbers from 1 up to \[n\],
\[n!=n(n-1)(n-2)(n-3).........1\] This special numerical concept is vital for calculating permutations and combinations, serving as a valuable analytical tool for problem-solving. Factorials are instrumental in revealing the various possible arrangements of objects, making them an essential component in mathematical and computational applications.
The factorial calculator computes the product of all positive integers up to a given non-negative integer \[n\].
Combination Calculator, \[\mathrm{^nC_k}\]


Answer

Combination \[C(n,k)\] formula, where \[ k \leq n\] is defined as
\[ \binom{n}{k} = \frac{n!}{k!(n-k)!}\] The formula is typically expressed as \[^nC_k\]. In mathematics a combination refers to the act of selecting items from a set with distinct members, wherein the order of selection holds no significance. These selections are representative of the various ways objects can be chosen from a given set, with \[n\] denoting the total number of objects and \[k\] representing the specific number of objects chosen.
The Combination Calculator determines the number of possible subsets that can be formed by selecting items from a larger set, regardless of the order of selection.
Permuation Calculator, \[\mathrm{^nP_k}\]


Answer

Permuation \[P(n,k)\] formula, where \[ k \leq n\] is defined as
\[ \binom{n}{k} = \frac{n!}{(n-k)!} \] The formula is typically expressed as \[^nP_k\]. It is a mathematical approach to find the quantity of potential arrangements within a specific set by taking into account the of order of selection (unlike combination). In this context, \[n\] represents the total count of objects under consideration, whereas \[k\] denotes the specific number of objects designated for selection.
The Permutation Calculator calculates the number of distinct arrangements or ordered subsets that can be formed by selecting items from a larger set.
