8.PS.1 Unit Flashcard

Front

What is the probability of rolling a number greater than 4 on a number cube?

Back

The probability is 1/3, as there are 2 favorable outcomes (5 and 6) out of 6 possible outcomes.

Front

What is the probability of tossing tails on a coin?

Back

The probability is 1/2, as there are 2 possible outcomes (heads or tails).

Front

What is the combined probability of rolling a number greater than 4 and tossing tails?

Back

The combined probability is (1/3) * (1/2) = 1/6.

Front

What is the probability of rolling a die and landing on a 4?

Back

The probability is 1/6, as there is 1 favorable outcome out of 6 possible outcomes.

Front

What is the probability of rolling a die and landing on any even number?

Back

The probability is 1/3, as there are 3 favorable outcomes (2, 4, 6) out of 6 possible outcomes.

Front

What is the probability of rolling a 4 and then rolling any even number?

Back

The combined probability is (1/6) * (1/3) = 1/18.

Front

What does it mean for events to be independent?

Back

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

Front

What does it mean for events to be dependent?

Back

Dependent events are those where the outcome of one event affects the outcome of another.

Front

If a marble is drawn from a bag and not replaced, what type of event is this?

Back

This is a dependent event because the outcome of the first draw affects the second draw.

Front

What is the probability of drawing a red marble first and a blue marble second from a bag containing 5 red and 3 blue marbles (without replacement)?

Back

The probability is (5/8) * (3/7) = 15/56.
