Sample Space and Theoretical Probability Basics

Front

What is a sample space?

Back

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

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of outcomes.

Front

What is the theoretical probability of rolling an 8 on a standard number cube?

Back

0, because a standard number cube has faces numbered 1 to 6.

Front

If a spinner has 2 red, 3 purple, 2 yellow, and 1 blue section, how many total sections are there?

Back

8 sections (2 + 3 + 2 + 1 = 8).

Front

What is the probability of landing on red or orange if a spinner has no orange sections?

Back

0, because there are no orange sections.

Front

How do you calculate the probability of an event?

Back

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

Front

What is the probability of landing on 7 if a spinner has sections numbered 1 to 8?

Back

25%, because there is 1 favorable outcome (landing on 7) out of 4 total outcomes.

Front

What does it mean to find the probability of not landing on a certain color?

Back

It means calculating the probability of landing on all other colors except the specified one.

Front

If a spinner has 3 red, 2 blue, and 1 green section, what is the probability of landing on blue?

Back

2/6 or 1/3.

Front

What is the probability of landing on red or purple if a spinner has 2 red and 3 purple sections?

Back

5/8.
