Sample Space and Tree Diagrams

Front

What is a sample space?

Back

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

How do you calculate the total number of combinations when rolling a die, spinning a spinner, and flipping a coin?

Back

Multiply the number of outcomes for each event: 6 (die) x 8 (spinner) x 2 (coin) = 96 combinations.

Front

What is a tree diagram?

Back

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

If you have 5 pairs of jeans, 8 t-shirts, and 2 pairs of shoes, how many outfits can you create?

Back

80 outfits (5 x 8 x 2 = 80).

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on all possible outcomes.

What is experimental probability?

Back

Experimental probability is the likelihood of an event occurring based on actual results from experiments.

Front

How do you find the probability of an event?

Back

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

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

Back

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

What is the probability of pulling a green marble from a bag with 8 green marbles and 17 other marbles?

Back

8/25, since there are 8 favorable outcomes out of 25 total marbles.
