Question

Write a complete C++ program.
The Mathematics department of Durham High school wants a programdeveloped that will illustrate basic probability for their studentsin a fun way. In particular they want a program called "LittleLotto" that stimulates a lottery. In this program students canspecify the number of numbers in the selection set (1-12) and thenumber of numbers patrons must pick and match to the winningnumbers (between 1 and size of the selection set). It will reportthe patron's chance of winning as both a number and aprobability.

________________________________________________________________________________
Example output:

This program will tell you the probabilty of winning " LittleLotto".

How many numbers (1-12) are there to pick from? 12
How many numbers must you pick to play?   5

Your chance of winning the lottery is 1 chance in 793.
This is a probabilty of 0.0013.
_____________________________________________________________________________
a. Write a function to compute the number of ways a set of k itemscan be selected from a set of n items (n >= k). The functionprototype is given as the following:

int computeways (int n, int k);

Hint:    n    = n(n-1)(n-2).....(n-k+1)        calculate in factorial   n! / k! (n-k)!
                 _________________
           k         1(2)(3)......(k)

b. Write a main function that ask user to specify n and k, and telluser the chance of winning as both a number and probabilty.


Here is my code
#include "stdafx.h"
#include <iostream>

using namespace std;

int factorial (int n)
   {
       if (n == 0)
           return1;
       else
           return n *factorial (n-1);
   }
   int main ()
   {
       (factorial (n - k)) /((factorial (n));
   }

Explanation / Answer

please rate - thanks #include #include using namespace std; int factorial (int); int computeways(int,int); int main () {int n,k,ways; double percent; cout
