uRandom Number Generation in Accordance with Binomial Distribution (RanBin#)

This function generates random integers in accordance with binomial distribution based on values specified for the number of trials n and probability p.

RanBin# (n, p [,m]) 1 < n < 100000 1 < m < 999 0 < p < 1

Omitting a value for m returns a generated random number as-is. Specifying a value for m returns the specified number of random values in list form.

Example

Operation

 

 

RanBin# (5, 0.5)

K6(g)3(PROB)4(RAND)4(Bin)

(Randomly produces the number of heads

5,0.5)w

that can be expected in accordance with

 

binomial distribution for five coin tosses

 

where the probability of heads is 0.5.)

 

RanBin# (5, 0.5, 3)

K6(g)3(PROB)4(RAND)4(Bin)

(Performs the same coin toss sequence

5,0.5,3)w

described above three times and displays

 

the results in a list.)

With polar coordinates,  can be calculated and displayed within a range of –180°<  < 180° (radians and grads have same range).

Be sure to specify Comp for Mode in the Setup screen.
