Vocabulary
This is the set of all possible outcomes of an experiment.
Answer: Sample space
How many outcomes are in the sample space when rolling a standard die?
6
Probability can be greater than 1.
Answer: False
Performing an experiment once is called this.
Answer: Trial
This word describes the result of a single experiment.
Outcome
What is the sample space when rolling a die?
Answer: {1, 2, 3, 4, 5, 6}
Probability cannot be negative.
Answer: True
If you flip a coin 10 times, the number 10 represents this.
Answer: Number of trials
This is a subset of the sample space.
Event
This event describes rolling 2, 4, or 6. What is the name of event?
Answer: Getting an even number
If probability is close to 0, the event is very likely.
Answer: False
If an event happens 4 times in 10 trials, the experimental probability is:
Answer: 4/10
This measures how likely an event is to happen.
Probability
What is the probability of rolling a 3 on a fair die?
Answer: 1/6
If probability is close to 1, the event is very likely.
Answer: True
If you roll a die 20 times and get a 6 five times, what is the experimental probability?
Answer: 5/20 or 1/4
Another name for experimental probability.
Answer: Relative frequency
What is the probability of rolling an even number on a fair die?
Answer: 3/6 or 1/2
Experimental probability is found by repeating trials.
Answer: True
The fraction of times an event occurs during trials is called this.
Answer: Relative frequency
