Question

In C++

Create a program that rolls two dice. It should roll these dice multiple times to find the probability of having the sum of the rolls add to 7. You should use a loop to roll the dice and use a counter to keep track of how many times they add to seven.

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

int main() {
    srand(time(NULL));
    int count = 0, total = 100000;
    for (int i = 0; i < total; ++i) {
        if ((1 + rand()%6) + (1 + rand()%6) == 7) {
            ++count;
        }
    }
    cout << "the probability of having the sum of the rolls add to 7 is " << count/(double)total << endl;
    return 0;
}
