Probability + Binomial Distribution Flashcards
What is a sample space diagram?
A table that shows all the possible outcomes of events
What is theoretical probability?
What is experimental probability?
What is the expected frequency?
What is the difference between a “subset” and a “proper subset”?
Draw the Venn diagram for :
A U B
A ∩ B
A’
A ∩ B’
What does it mean for two events to be mutually exclusive?
They cannot happen at the same time
How would you represent the probability of being mutually exclusive and not mutually exclusive? (With equation)
What does it mean for two events to be independent? And equation
They have no affect on each other
What does this notation mean?
represnt the following information as a
* sample space
* distribution as a table
* distribution as a function
What is discrete uniform distribution?
A probability distribution with all equal likely outcomes
How would you calculate the expected value ?
What is a binomial probability distribution?
Binomial coefficients are used to determine the probability of an event happening
What are the conditions required for probability being able to be calculated using binomial distribution?
- F ixed number of (n) trials
- Independnat outcomes
- C onstant probability of success (p)
- T wo outcomes : success & failure
How is a random variable X who’s outcome is the number of successes by being distributed Binomially?
