Probability Sample Space

Front

What is a sample space in probability?

Back

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

Front

What does it mean to calculate the probability of an event?

Back

Calculating the probability of an event means determining the likelihood of that event occurring, expressed as a fraction of the total number of outcomes.

Front

How do you find the probability of an event happening?

Back

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

Front

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 six possible outcomes.

Front

What is the probability of flipping heads on a fair coin?

Back

1/2, since there are two possible outcomes (heads or tails) and one favorable outcome (heads).

Front

What is a tree diagram in probability?

Back

A tree diagram is a visual representation that shows all possible outcomes of a probability experiment, branching out from each decision point.

Front

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

Back

1/4, since there is one favorable outcome out of four possible outcomes.

Front

What does 'at least' mean in probability?

Back

'At least' means that the event can occur with the specified number or more. For example, 'at least 2 girls' means 2 or more girls.

Front

How many outcomes are there when rolling 2 dice?

Back

36 outcomes, since each die has 6 faces (6 x 6 = 36).

Front

What is the probability of NOT rolling a 1 on a die?

Back

5/6, since there are 5 outcomes that are not 1 out of 6 possible outcomes.
