Intermediate Mathematics - Discrete probability distribution
Discrete probability distribution
The discrete probability distribution of a random variable is given by its
possible values together with their probabilities.
This distribution may be displayed as a table or a graph or sometimes, as
a formula. First list all the possible values, x, that X can take. Then
calculate the associated probabilities, Pr(X = x). Remember that the total
probability = 1.
Give the probability distribution for X, the number on the face of a die
that will be uppermost after it is rolled.
Give the probability distribution for _N,_ the number of heads obtained,
when a fair coin is tossed three times.
