u Random 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 RanBin# (5, 0.5) (Randomly produces the number of heads 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) (Performs the same coin toss sequence described above three times and displays the results in a list.)
