Understanding Probability Basics

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, or as a percentage.

What is a standard die?

Back

A standard die is a cube with six faces, each showing a different number from 1 to 6.

Front

What is the probability of rolling a specific number on a standard die?

Back

The probability of rolling a specific number (like a 3) on a standard die is 1 out of 6, or approximately 16.7%.

Front

What is the probability of getting heads when tossing a fair coin?

Back

The probability of getting heads when tossing a fair coin is 50%.

Front

What is the probability of getting tails when tossing a fair coin?

Back

The probability of getting tails when tossing a fair coin is also 50%.

Front

What is a probability experiment?

Back

A probability experiment is a process or action that leads to one or more outcomes, such as rolling a die or tossing a coin.

Front

Why is it important to conduct multiple trials in a probability experiment?

Back

Conducting multiple trials helps confirm the theoretical probability and provides a more accurate estimate of the actual probability.

What is a marble probability problem?

Back

A marble probability problem involves calculating the likelihood of drawing a specific colored marble from a collection.

Front

If there are 10 marbles in a bag, 3 of which are green, what is the probability of pulling out a green marble?

Back

The probability of pulling out a green marble is 3 out of 10, or 30%.

What is a spinner in probability?

Back

A spinner is a circular object divided into sections, each representing a different outcome, used in probability experiments.
