Someone Help Me Out Plssss With Some C Programming by eesaah(m): 8:43am On Sep 18, 2007 |
Pls someone should help me with a C or C++ program for binomial probability computation. the formular is: probability={n!/((n-x)!*x!)}*(P^x)*((1-P)^(n-x)) Where; n!= n factorial, x!=x factorial n,x,p are all variables Thanks |

The Thing about most of these is that is you search online for a while you will find a lot of tutorials and articles to help you do your assignment. The Key is to search and google.com provides you with a great search tool . Here is a link for you, if you need more, please google http://www.codeproject.com/cpp/calc_prob.asp Kobojunkie |

I dont av C/C++ IDE here to compile a C/C++ program. But if u dont mind, this is a simple C# version for it. A C# console program, written and tested working fine! using System; class binomial_probability { static void Main(string[] args) { int x = 2, n = 5; float p = 0.1265f; double prob = Probability(x, n, p); Console.WriteLine("Binomial Probalibity for x={0}, n={1}, P={2} is {3}", x, n, p, prob); } public static long Factorial(int n) { long fact = 1; if (n > 0) { for (long i = 1; i <= n; i++) fact *= i; } else fact = 0; return fact; } public static double Probability(int x, int n, float p) { //probability={n!/((n-x)!*x!)}*(P^x)*((1-P)^(n-x)) double prob = (Factorial(n) / Factorial(n - x) * Factorial(x)) * Math.Pow(p, x) * Math.Pow((1 - p), (n - x)); return prob; } } Have a great day |
