How to calculate the number of possible combinations?
In general, if there are n objects available. And out of these to select k, the number of different combinations possible is denoted by the symbol nCk. The number of subsets, denoted by nCk, and read as “n choose k.” will give the combinations.
Which is the k-combination of a set?
More formally, a k -combination of a set is a subset of k distinct elements of S. If the set has n elements, the number of k -combinations is equal to the binomial coefficient. The combination is a type of permutation where the order of the selection is not considered.
Why do you need to know the formula for combination?
In simple words, combination involves the selection of objects or things out of a larger group where order doesn’t matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set. It shows how many different possible subsets can be made from the larger set.
How to write the chemical formula of a compound?
To write the chemical formula of a binary compound. Determine the valencies of the two elements present. Write the chemical formula such that the sums of the valencies of the two elements are equal. Do this by determining the lowest common multiple of the two valencies.
