Sample Spaces & Probability Practice

Front

What is a sample space in probability?

Back

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

What does it mean to flip a coin in probability?

Back

Flipping a coin is a random experiment with two possible outcomes: heads or tails.

Front

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

Back

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

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

If a bag contains 5 red balls and 5 green balls, what is the probability of picking a green ball?

Front

What is a tree diagram in probability?

Back

A tree diagram is a visual representation of all possible outcomes of a probability experiment, showing the branches for each choice.

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.

Front

How do you calculate the probability of two independent events occurring?

Back

Multiply the probabilities of each event: P(A and B) = P(A) x P(B).

What is the sample space for rolling a six-sided die?

Back

The sample space is {1, 2, 3, 4, 5, 6}.
