dependent events | two or more events for which the occurrence of one affects the probability of the other(s) |
event | a collection of possible outcomes, often describable using a common characteristic, such as rolling an even number with a die or picking a card from a specific suit |
event space | the set of possible outcomes in an event: for example, the event “rolling an even number” on a die has the event space of 2, 4, and 6 |
factorial | an abbreviated way of writing a product of all whole numbers from 1 to a given number, indicated by that number followed by an exclamation point, as in 3! = 3 • 2 • 1 |
Fundamental Counting Principle | a way to find the number of outcomes in a sample space by finding the product of the number of outcomes for each element |
independent events | two or more events for which the occurrence of one does not affect the probability of the other(s) |
outcome | a result of a trial |
permutations | groupings in which the order of members matters |
probability | a measure of how likely it is that something will occur |
sample space | the set of all outcomes |
