compound event an event consisting of two or more simple events
event the desired outcome or set of outcomes in a probability experiment.
experimental probability an estimate probability based on the relative frequency of positive outcome occuring during an experiment. It is based on what actually occurred during an experiment . It is based on what actually occurred during such an experiment
likelihood the chances of an event occuring
outcome any one of the possible results of an action. for example 4 is an outcome when a number cube is rolled.
probability the chances that some event will happen. it is the ratio of the number of flavor able outcomes to the number of possible outcomes.
probability experiment when you perform an event to find the likelihood of an event.
relative frequency a ratio that compares the frequency of each category to a total
relative frequency bar graph a graph used to organize occurrence compared to a total
relative frequency table a table used to organize occurrence compared to a total
sample space The set of all possible outcomes of a probability experiment
simple event one outcome or a collection of outcomes.
simulation an experiment that is designed to model the action in a given situation.
theoretical probability of a com[pound event the ratio of the number of ways an event can occur ro the number of possible outcomes in the sample space. It is based on what should happen when conducting a probability experiment.
tree diagram a diagram used to show the sample space
uniform probability model a probability model which assigns equal probability to all outcomes.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
