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.

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

What is theoretical probability?

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a sample space.

Front

How do you calculate the probability of an event?

Back

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

Front

What is a tree diagram?

Back

A tree diagram is a visual representation that shows all the possible outcomes of a probability experiment.

Front

If a spinner has 4 equal sections, what is the probability of landing on any one section?

Back

1/4, since there are 4 equal sections.

Front

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

Back

1/6, since there are 6 faces on a die.

Front

When flipping a coin, what are the possible outcomes?

Back

Heads or Tails.

Front

How many outcomes are there when rolling a die and flipping a coin?

Back

12 outcomes (6 outcomes from the die x 2 outcomes from the coin).

Front

What is the probability of pulling a red marble from a bag containing 3 red, 2 blue, and 5 green marbles?

Back

3/10, since there are 3 red marbles out of 10 total marbles.
