<u>Combinations and Permutations</u>
Combinatorics is the part of the discrete mathematics that studies the enumeration of groups or sorting of a determined number of elements. The concept of combinations is tied to the different forms to group elements where the order of their arrangements is not important or does not differentiate from the very same set of elements picked in a different order.
The concept of combinations is tied to the differents forms to group elements where the order of their arrangements is not important or does not differentiate from the very same set of elements picked in different order.
On the other hand, permutations or variations are sets selected in a specific order and another set with the same element but in different order is considered a different set.
If we have n elements available to pick from in sets of m elements each, there can be C(n,m) different combinations, and it's given by
Similarly the number of permutations is given by
(a) I have n=21 songs to pick from and I want to choose m=8 of them where the order matters, so it's a permutation:
I can make more than 8 billion different setlists
(b) To choose m=4 songs from n=21 songs where the order does not matter, we compute the combination
I can make almost 6,000 sets of 4 songs
Answer:
Step-by-step explanation:
If our ratio is apple juice to orange juice, then the proportion will be
If we are looking for how much orange juice she needs if she uses 32 ounces of apple juice, then 32 goes on top of a new ratio and x goes on bottom:
That's the proportion. If you need to solve it, cross multiply to get
8x = 128 so
x = 16 ounces of orange juice
