Probability Concepts and Calculations

Front

What is probability?

Back

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

Front

What is theoretical probability?

Back

Theoretical probability is the probability calculated based on the possible outcomes of an event, assuming all outcomes are equally likely.

Front

What is experimental probability?

Back

Experimental probability is the probability determined by conducting an experiment and observing the outcomes.

Front

What is the formula for calculating probability?

Back

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

Front

What does the Law of Large Numbers state?

Back

The Law of Large Numbers states that as the number of trials increases, the experimental probability will get closer to the theoretical probability.

Front

If a spinner has 8 equal sections, what is the probability of landing on one specific color?

Back

1/8, since there is 1 favorable outcome and 8 possible outcomes.

Front

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

Back

1/2, since there are 3 even numbers (2, 4, 6) out of 6 possible outcomes.

Front

How do you find the probability of multiple independent events occurring?

Back

Multiply the probabilities of each individual event.

Front

What is a sample space in probability?

Back

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

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event for which probability is being calculated.
