Math 7th Grade Probability Vocabulary

Complementary Events

• A game where there is not a chance of each player being equally likely to win

• The events of one outcome happening and that outcome not happening. The sum of the probabilities of an event and its complement is 1 or 100%.

• An event consisting of two or more simple events

• The ratio of the number of ways an event can occur to the number of possible outcomes. It based on what should happen when conducting a probability experiment

Compound events

• A game where each player has an equally likely chance of winning

• Two or more events in which the outcome of one event does not affect the outcome of the other events

• An arrangement, or listing, of objects in which order is important

• An event consisting of two or more simple events

Dependent Events

• Two or more events in which the outcome of one event affects the outcome of other events

• The chance that some event will happen. It is the ratio of the number of favorable outcomes to the number if possible outcomes

• A ratio that compares the frequency of each category to the total

• The set of all possible outcomes of a probability experiment

Experimental Probability

• One outcome or a collection of outcomes

• Any one of the possible results of an action. For example, 4 is an outcome when a number cube is rolled

• An estimated probability based on the relative frequency of positive outcomes during an experiment. It is based on what actually occurred during such an experiment

• Outcomes occur at random if each outcome occurs by chance. For example, rolling a number on a number cube occurs at random

Fair Game

• An experiment hat is designed to model the action in a given situation

• A game where each player has an equally likely chance of winning

• The chance that some event will happen. It is the ratio of the number of favorable outcomes to the number if possible outcomes

• An arrangement, or listing, of objects in which order is important

Fundamental Counting principle

• Two or more events in which the outcome of one event affects the outcome of other events

• An estimated probability based on the relative frequency of positive outcomes during an experiment. It is based on what actually occurred during such an experiment

• Uses multiplication of the number of ways each events in an experiment can occur to find the number of possible outcomes in a sample space

• The events of one outcome happening and that outcome not happening. The sum of the probabilities of an event and its complement is 1 or 100%.

Independent Events

• Two or more events in which the outcome of one event does not affect the outcome of the other events

• One outcome or a collection of outcomes

• A diagram used to show the sample space

• A probability model which assigns equal probability to all outcomes

Outcome

• Uses multiplication of the number of ways each events in an experiment can occur to find the number of possible outcomes in a sample space

• A probability model which assigns equal probability to all outcomes

• Any one of the possible results of an action. For example, 4 is an outcome when a number cube is rolled

• A ratio that compares the frequency of each category to the total

Permutation

• The chance that some event will happen. It is the ratio of the number of favorable outcomes to the number if possible outcomes

• A ratio that compares the frequency of each category to the total
