Permutations

Conclusion:Before learning about permutations, probabilities didn't make much sense to me. I didn't understand how they arrived at all those statistics for probabilities. Now, I've seen the LIGHT of probabilities, and I get it! Real life situations in which I can use this method would be calculating the odds in games of chance. It is also used in the lottery when boxing numbers. Over all, it was very easy to get this topic, now the challenge is to put it all together and have an understanding on the rest of the topics.
