### Probability

1. 1.
2. 2.
3. 3. Why do we need Probability?<br />Probability is needed to find the likelihood to something occurring at a point in time.<br />
4. 4. Definition of Probability<br /><ul><li>Probability is the measure of how likely it is the some event will occur, a number expressing the ratio of favorable cases to the whole number or cases possible.
5. 5. For example the chance of a coin landing on heads is 50%. This is because a coin has two sides so there is a 50% chance that the coin will land on heads and 50% that a coin will land on tails.</li></li></ul><li>Definition of Experimental Probability<br /><ul><li>Experimental Probability is the chance of something happening, based on repeated testing and observing results. It is the ration of the number of times an even has occurred to the number of times it has been tested.
6. 6. For example to find the probability of getting a six when rolling a dice, you need to roll the dice many times, then divide the number of times who rolled a six with how many times you rolled the dice in total.</li></li></ul><li>So in this particular experiment the chance of rolling a two was the highest because there is ⅙ chance that each face of the dice will be rolled, but this particular time I conducted this experiment the number two was rolled the most and the number four the least.<br />
7. 7. Where is Probability Used?<br />Probability is used a lot in daily life, Probability is used in such as Math, Statistics, Finance, Gambling, Science, Machine and Artificial Intelligence, and in many other activities.<br />
8. 8. The Experiment and the Outcome<br />An experiment is controlled test or investigation conducted by someone. And an outcome is the the result of these tests.<br />For Example:<br />If you spin a spinner that consists of the color Pink, Blue, Green and Purple, then having the spinner stop on any of these colors is a possible outcome.<br />
9. 9. Win? Lose? Tie? Likely? Unlikely? Certain? <br />The outcome of a experiment differs for each experiment for example if you have a spinner that looks like this:<br />Then which color is it mostly likely to land on when spun? Blue, White, Black, Yellow or Red? Which one is least likely? Does anything tie here?<br />
10. 10. Activities<br />
11. 11. Word Search<br />Now, you will receive a Word Search, the goal of a Word Search- incase you didn’t know is to find all the hidden words. <br />Good Luck <br />
12. 12. Online Game<br />Okay, now for a fun activity you get to play a game. You can choose whichever game you want to play, so Google “Probability Games” and choose any of the first few. Have fun and play around and test your Probability Knowledge.<br />
13. 13. What did you learn?<br />Now, I will hand out a Sticky Note to each person and on it you have to write down one thing you learnt about Probability.<br />
