Exploring Concepts of Probability

This activity contains 9 questions.

## Older children, but not yet younger children, understand that chance

 is the same as luck. has a memory and depends on previous results. means some results are more or less likely than others. makes everything equal.

## All of the following are true about probability EXCEPT

 Probability changes based on the number of trials. Experimental probability gets closer to theoretical probability with a larger data set. Probably of an event is a measure of the likelihood of an event occurring. Probability can be determined in two ways: theoretically and experimentally.

## In a probability experiment, an event

 must be part of a two-stage or multistage experiment. must be part of a single-stage experiment. is always the same as the sample space. is a subset of the sample space.

## All of the following are tools for solving probability problems EXCEPT

 Formula Area model Tree diagram Matrix

## Independent events

 are the same thing as multistage events. are when the occurrence or nonoccurrence of one event has no effect on the other. are when the probability of one event depends on the result of the first event. must be in a single-stage experiment.

## Describe what is meant by theoretical and experimental probability and give an activity that emphasizes the difference.
