Methods of Signal Indication with Flags - Permutations and Combination Problems
Learn to Solve permutation combination problems- This tutorial will show you all the methods to indicate two flag signals out of 6 flags of different colors. While creating signal, both color should be different. So first flag can be chosen any from 6 , so we have 6 ways to choose first signal flag and since we can not repeat color so , now we are left with 5 color for another signal, so altogether , from fundamental principle of counting we have, 6.5 = 30 methods to indicate signals with 2 flags of different colors.
There are similar so many types of Permutations and Combination Problems, we are learning to solve each type of question from this math chapter by both using permutation formula or by Fundamental Principle of Counting.
