Lessons 9-3 and 9-5 Practice

Front

What is a tree diagram?

Back

A tree diagram is a visual representation that shows all possible outcomes of a sequence of events, often used in probability.

Front

How do you calculate the total outcomes when rolling a die and flipping a coin?

Back

Multiply the number of outcomes for each event: 6 (die) x 2 (coin) = 12 total outcomes.

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a ratio of favorable outcomes to total outcomes.

Front

How do you find the probability of rolling a number greater than 4 on a die?

Back

There are 2 favorable outcomes (5 and 6) out of 6 total outcomes, so the probability is 2/6 or 1/3.

Front

What is the probability of drawing a blue marble from a bag with 4 red, 2 blue, and 3 green marbles?

Back

The probability is 2 (blue marbles) / 9 (total marbles) = 2/9.

Front

How do you calculate the total number of combinations for a car model with multiple options?

Back

Multiply the number of options for each category: 4 trim levels x 5 colors x 3 interiors = 60 combinations.

Front

What is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes).

Front

If you flip a coin and roll a die, how many total outcomes are there?

Back

There are 12 total outcomes (6 outcomes from the die and 2 from the coin).

Front

What is the probability of drawing a blue marble and flipping heads?

Back

The probability is (2/9 for blue marble) x (1/2 for heads) = 2/18 = 1/9.

Front

How do you represent outcomes using a list table?

Back

A list table organizes all possible outcomes in rows and columns, making it easier to visualize combinations.
