Probability Flashcards
What are independent events
Events where the outcome of one event has no effect on the other
What is the formula that shows events are independent
What is conditional probability
Events where the probably of an event can change depending on the outcome of a previous event
What is the symbol used to show conditional probability
A vertical line
What is a random variable
A variable whose value depends on the outcome of a random event
What is the range of values that a random variable can take called
Its sample space
What does a discrete variable mean
It can only take certain number values
What is the notation for: the probability that the random variable, X, takes a particular value, x
P(X=x)
What is it called when all the probabilities of every situation are the same, e.g. the probability of 1,2,3,4,5 and 6 are all the same on a fair dics
Discrete uniform distribution
How can you use notation to show that the sum of the probabilities of all outcomes of a random variable add up to 1
Give the probability mass function for this table
.
Give the formula to work out the probability of x successes from n trials
