TEKS 7.6 Probability

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, where 0 means the event cannot happen and 1 means the event is certain.

Front

What is a tree diagram in probability?

Back

A tree diagram is a visual representation that shows all the possible outcomes of an event, branching out from a starting point to illustrate different paths.

Front

How do you calculate the probability of an event?

Back

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

Front

What does it mean for events to be independent?

Back

Independent events are those whose outcomes do not affect each other. The occurrence of one event does not change the probability of the other.

Front

What is a sample space?

Back

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

Front

If a coin is tossed, what are the possible outcomes?

Back

The possible outcomes when tossing a coin are Heads (H) and Tails (T).

Front

What is the probability of rolling a 3 on a standard six-sided die?

Back

The probability of rolling a 3 is 1/6, since there is one favorable outcome (rolling a 3) out of six possible outcomes.

Front

How do you find the probability of multiple independent events occurring?

Back

To find the probability of multiple independent events occurring, multiply the probabilities of each individual event.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes in a perfect world, while experimental probability is based on actual results from experiments.

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that is considered successful for the event being measured.
