Definition: A combination is a arsenal or set of the aspects such that the order of the plan of elements doesn"t matter. It is a prevalent approach to discover the complete variety of combinations of aspects current in an occasion . It is dedetailed by C(n,r) .

You are watching: Indicate the formula for the following conditions. pc(n, r) =

The formula for the number of combinations of n things taken r at a time is given by :-

n!/r!(n-r)!

The formula is the exact same as the combicountry formula other than for the multiplication of r! in the denominator.

nCr = n! / (r!(n-r)!),

Step-by-step explanation:

The formula for C(n,r), additionally recognized as "n choose r" or a combination,

is:

nCr = n! / (r!(n-r)!),

where n is the full number of alternatives and also r is number you should choose

The number created is the full number of feasible combicountries.

The ! suggests factorial. For instance, 4! = 4 x 3 x 2 x 1

The formula is a permutation in which n represents the sample points in the collection, while r represents the variety of sample points in each permutation.

The formula for C(n,r), likewise well-known as "n choose r" or a mix,is: nCr = n! / (r!(n-r)!), wbelow n is the complete variety of alternatives and r is number you must chooseThe number generated is the complete number of feasible combicountries. The ! implies factorial. For instance, 4! = 4 x 3 x 2 x 1
