BinomialIntegerRV

public BinomialIntegerRV(double prob,
 int n)
                  throws IllegalArgumentException

Constructor.

Parameters:

prob - the probability that a try is successful.

n - the number of tries (must be positive)

Throws:

IllegalArgumentException

Method Details

getProb

public double getProb()

Get the probability that a try succeeds.

Returns:

the probability that a try succeeds

getN

public int getN()

Get the number of tries for this random variable.

Returns:

the number of tries

next
