| Term | Definition |
|---|
| area model | A diagram in which fractions of the area of the diagram correspond to probabailities in a situation |
| binomial probabaility | the likelyhood of getting one of two outcomes ((like heads or tails)) |
| equally likely | two or more events that have the same probability of occuring. ((like tossing a fair coin)) |
| expected value (or long term average) | Intuitively the average payoff over the long run. Like in a number cube 3 has 1/6 of a chance, if u roll 36 times u can expect to roll 3 6 times |
| experimental probabaility | A probabaility that is determined by experiments. Like tossing a coin and conting how many times it lands heads and making it into a probabaility |
| fair game | A game in which each player has a equally likely to win. Like flipping coins if lands heads up, a player gets a point and visa versa. U can change a unfair game to fair by changing the scoring |
| Law of Large Numbers | It means that the higher tmes u conduct a experiment, the closer it would get to the theoretical probabability |
| outcome | a possible result (like on a fair coin the outcome can be heads or tails) |
| payoff | the number of points or dollars a player recieves in a game for a particular outcome |
| probability | a number between 1 and 0 that describes the number of times the likelyhood will occur. Like the probabaility of getting heads is 1/2. a certain ____ is 1 and a impossible is 0 |
| random | Outcomes that are uncertain when viewed individually bt which exhibit a particular pattern over the long run are ______ Like when u roll a number cube u do not know what number u will get but u do know that u will rolll the numbers the same amounts of times |
| sample space | the set of all possible outcomes in a probabaility situation. Like when u toss two fair coins the sample space is 4 outcomes: HH HT TH AND TT |
| theoretical probability | A probabaility obtained by anylizing a situation. Example: there are 36 likely outcomes when 2 number cbes are rolled of these six have a sm of 7 so the so the probabaility of rolling 7 is 6/36 |
| tree diagram | a daigram used to determine the number of possible outcomes in a probability situation. The numebr of final outcomes is equal to the number of possible outcomes. |
