Probability

PB MG Here are some helpful definitions for probablity. An **experiment** is a situation involving chance or probability that leads to results called outcomes. An **outcome** is the result of a single trial of an experiment. An **event** is one or more outcomes of an experiment. And finally, **probability** is the measure of how likely an event is.

Remember if there is an equal probability, no matter the results of past experiments, the probability will always stay the same. JJ PF

In probability, the fraction is __outcome__ all possible outcomes. PF VW

Always remember that probability is something that would be accurate in the perfect world of math. In the real world results will most often be different PF TA

Finding probability of picking out two things is simple. If it says you bag of marbles, 3 blue 4 green and 5 red and you need to find out the probability of picking a green then replacing then picking a red marble you need to first find the total (in this case its 12) of all of the items. After that create the amount of the color over total for both of them (in this case its 4 over 12 and 5 over 12). After that you multiply them (remember its denominator time denominator and that goes in the denominator spot, and then the same thing for the nominator but in the nominator spot). PB-NS
