Theoretical Probability
What is theoretical probability?
Theoretical probability is the ratio of the number of favorable outcomes to the number of possible outcomes. Or what SHOULD happen
What's the compound probability of flipping a coin twice and getting tails both times?
50/50 chance.
What is a tree diagram?
A tree diagram is a tool in the fields of general mathematics, probability, and statistics that helps calculate the number of possible outcomes of an event or problem, and to cite those potential outcomes in an organized way.
What is experiment probability?
What ACTUALLY happens.
What is a probability model?
A probability model is a mathematical representation of a phenomenon.
What is the probability of rolling the dice and getting a 3?
1/6.
What is compound event in probability?
If an event has more than one sample point.
What can a tree diagram be used for?
A file system.
What is an example of experiment probability?
Flipping a coin, picking a card in a deck of cards, ect.
How can probability models help you decide in decision-making?
Deciding whether or not to play a game where the outcome may not be immediately obvious.
How do you determine a theoretical probability question?
You need to have knowledge of the situation to find the probability.
How many outcomes are there in a compound event?
One or more.
How are tree diagrams used in real life?
Tree diagrams display all of the possible outcomes for each event.
With a dice what is the experiment probability of rolling a 4?
24%.
What should the probability of any event be?
Equal to or greater than 0 and less than or equal to 1
What's the theoretical probability of rolling a dice and getting a 4 or 5?
2/6.
What is an example of compound probability?
Flipping two coins and finding out the probabiltiy.
What is an advantage of using a tree diagram?
To provide clear visualization and are easy and precise to read.
If you flip a coin 40 times with experiment probability is possible to get 20 heads and 20 tails?
Yes even though that is the theoretical probability it is possible.
Why are probability models important?
Probability models are important because they create a simple yet comprehensive explanation of known phenomena.
What's the theoretical probability of rolling a dice and not getting a 4?
5/6.
In a deck of cards of 51 with only 1 king, what is the probability of grabbing a king?
1/51.
What is a tree diagram represented for?
A tree diagram may be used to represent a probability space.
How is theoretical probability and experiment probability different?
Theoretical probability is when you flip a coin 10 times and you are supposed to get 5 heads and 5 tails. The experiment probability is when you flip the coin 10 times and get an uneven answer such as 7 heads and 3 tails.
What are the set of all outcomes named?
Sample space.
