Answer 1

Answer:

One very simple trick is to look for what set of things is given on the question

Step-by-step explanation:

For example of it asks for number of handshakes between people then it's a combination question as a handshake between person A and B and is same as a handshake between B and A...

One example for permutations is words in a dictionary... As we can see AND is different from DAN... The letters are same still order matters...

In conclusion... Permutation - order of things matter

In Combination - it doesn't matter..
