Theoretical and Experimental Probability

Front

What is theoretical probability?

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation.

Front

How do you calculate the theoretical probability of an event?

Back

Theoretical probability is calculated using the formula: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

Front

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

How is experimental probability different from theoretical probability?

Back

Experimental probability is based on actual experiments and observations, while theoretical probability is based on expected outcomes.

Front

What is the probability of an event that is certain to happen?

Back

The probability of an event that is certain to happen is 1 (or 100%).

Front

What is the probability of an event that is impossible?

Back

The probability of an event that is impossible is 0.

In the word 'ALGEBRA', how many letters are there in total?

Back

There are 7 letters in total in the word 'ALGEBRA'.

Front

What is the probability of choosing a letter other than 'A' from the word 'ALGEBRA'?

Back

The probability of choosing a letter other than 'A' is 5/7.

Front

What does it mean when we say probability is the chance that some event will occur?

Back

It means that probability quantifies the likelihood of an event happening, expressed as a number between 0 and 1.
