Basic Probability

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What does it mean if an event is 'impossible'?

Back

An impossible event has a probability of 0, meaning it cannot occur.

Front

What does it mean if an event is 'unlikely'?

Back

An unlikely event has a probability less than 0.5, indicating that it is not expected to happen.

What is the probability of landing on a specific section of a spinner divided into equal parts?

Back

The probability is calculated as the number of favorable sections divided by the total number of sections.

How do you calculate the probability of rolling an odd number on a standard six-sided die?

Back

There are three odd numbers (1, 3, 5) on a die, so the probability is 3/6 or 1/2.

Front

What is the probability of rolling a specific number with two dice?

Back

The probability of rolling a specific number with two dice is calculated by determining the number of combinations that result in that number divided by the total possible outcomes (36).

Front

How do you find the probability of drawing a specific color of marble from a jar?

Back

The probability is found by dividing the number of marbles of that color by the total number of marbles in the jar.

Front

What is the probability of an event that is 'certain'?

Back

A certain event has a probability of 1, meaning it will definitely occur.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes, while experimental probability is based on actual experiments and observed outcomes.
