100
The probability you get a heads on a basic 2 sided quarter
What is .5 or 1/2
100
A histogram that displays a discrete probability model when the outcomes are numerical.
What is Probability Histogram
100
List of all possible outcomes of a random phenomenon
What is Sample Space
200
A number between zero and one that gives the long run proportion of repetitions of a random phenomenon on which an event will occur
What is Probability
200
Events that have no outcomes in common
What is Disjoint Events
200
Branch of mathematics that counts arrangements of an object
What is Combinatorics
300
Any outcome or any set of outcomes of a random phenomenon.
What is an Event
300
The square root of the variance
What is Standard Deviation
300
The probability that an event does not occur is always one minus the probability that it does not occur
What is Complement Rule
400
The mathematical description of a random phenomenon consisting of two parts: a sample space [S] and a way of assigning probabilities to events.
What is Probability Model
400
If two events are disjoint, the probability that one or the other occurs is the sum of their individual probabilities
What is the Addition Rule
400
Probability model that assigns probabilities to each of a finite number of possible outcomes
Discrete Events
500
The probability that you will roll a 7 with 2 fair, 6-sided dice.
What is 6/36 or .16
500
The average of many independent random outcomes is approximately normally distributed. When we average "n" independent repetitions of the same random phenomenon, the resulting distribution of outcomes has mean equal to the mean outcome of a single trial and standard.
What is Central limit theorem
500
random phenomenon is repeated many times, the mean of the observed outcomes approaches the mean of the Probability model
What is Law of Large Numbers *DAILY DOUBLE
