How do You Figure Probability?

To figure out probability you must figure out the odds of something occurring or not occurring. Probabilities take the form of ratios. For example, a quarter has two sides, so if we were to flip it then the probability that it would come up one side or the other would be 1:2 or 1/2. There are two sides but only one will land facing upwards. If we were to take a standard 6 sided dice and roll it then the odds would be 1:6 or 1/6. If the situation allows for more than one outcome at a time then the first number may increase. For example, If we flip a two quarters the odds of the outcome would look like this 1/4 chance for both heads, 1/4 chance for both tails and 2/4 chances of a mixed result.
