Probability - Predictions (TEKS 7.6H)

Front

What is probability?

Back

Probability is the measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What does it mean for an event to be equally likely?

Back

An event is equally likely if it has the same chance of occurring as another event.

Front

What is a spinner in probability?

Back

A spinner is a circular device divided into sections, each representing a possible outcome when spun.

Front

What is a number cube?

Back

A number cube is a six-sided die, with each side showing a different number from 1 to 6.

Front

How do you calculate the probability of a single event?

Back

The probability of a single event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is the probability of rolling an even number on a number cube?

Back

The probability of rolling an even number (2, 4, or 6) is 3 out of 6, or 1/2.

Front

What does it mean for outcomes to be independent?

Back

Outcomes are independent if the occurrence of one event does not affect the occurrence of another event.

Front

What is a sample space?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is the probability of selecting a number less than 4 from a set of numbers 1-10?

Back

The probability is 3 out of 10, or 3/10, since the numbers less than 4 are 1, 2, and 3.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from trials.
