Warm-up Expected Value Day

Front

What is the definition of probability?

Back

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

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 spinning red on a spinner with equal sections?

Back

If the spinner has equal sections, the probability of spinning red is the number of red sections divided by the total number of sections.

Front

What is a tree diagram and how is it used in probability?

Back

A tree diagram is a visual representation of all possible outcomes of an event, used to calculate probabilities by showing the paths of outcomes.

Front

How do you find the total number of outcomes when rolling a die and flipping a coin?

Back

To find the total number of outcomes, multiply the number of outcomes for the die (6) by the number of outcomes for the coin (2), resulting in 12 total outcomes.

Front

What is the probability of two independent events occurring together?

Back

The probability of two independent events occurring together is the product of their individual probabilities.

Front

How do you calculate the probability of choosing a specific combination of items from a set?

Back

The probability of choosing a specific combination is calculated by dividing the number of favorable combinations by the total number of combinations possible.

Front

What is the probability of spinning green on a spinner with 4 equal sections?

Back

If there is 1 green section out of 4 total sections, the probability of spinning green is 1/4.

Front

What is the concept of independent events in probability?

Back

Independent events are events where the outcome of one event does not affect the outcome of another event.

Front

How do you determine the probability of multiple events occurring in sequence?

Back

To determine the probability of multiple events occurring in sequence, multiply the probabilities of each individual event.
