Flashcards in Statistics - Probability Deck (11):

1

## What is a sample space?

### Set of all possible outcomes

2

## What is an event?

### Collection of outcomes

3

## What is an experiment?

### A repeatable process that gives rise to a number of outcomes

4

## What is a Venn diagram?

###
Represents events graphically

Frequencies/probabilities are represented

5

## What is A and B in a Venn diagram?

### A intersection B

6

## What is A or B in a Venn diagram?

### A union B

7

## What are mutually exclusive events?

###
When events have no outcomes in common

Venn diagram circles don't overlap

8

## What are independent events?

###
When events have no effect on another

Probability of A is the same whether or not B occurs

9

## What is the equation for mutually exclusive events?

### P(A or B) = P(A) + P(B)

10

## What is the equation for independent events?

### P(A and B) = P(A) x P(B)
