L18: COMBINATORICS | Factorial, Permutation, Circular Permutation, Combinations | Discrete Math's

Full Course of Discrete Mathematics: Discrete Mathematics Lectures

In this video you can learn about COMBINATORICS Factorial, Permutation, Circular Permutation, Combinations in Foundation of Computer Science Course. Following topics of Discrete Mathematics Course are discusses in this lecture: COMBINATORICS Factorial, Permutation, Circular Permutation, Combinations with examples: How many different signals can be made by 5 flags from 8 flags of different colors, How many words can be made by using the letters of the word 'SIMPLETON' taken all at a time, How many permutations of the letters ABCDEFGH contains the string ABC, Circular Permutations Examples: In how many ways ten people can sit around a table, How many necklace of 12 beads each can be made from 18 beads of different colors, Combinations examples: how many poker hands of five cards can be dealt from a standard deck of 52 cards, Prove that C(n,r) = C(n,n-r), In how many ways can a cricket eleven be chosen our of 15 players? If a (i) particular player is always chosen, (ii) a particular player is never chosen . This topic is very important for College University Semester Exams and Other Competitive exams like GATE, NTA NET, NIELIT, DSSSB tgt/ pgt computer science, KVS CSE, PSUs etc
