Question

//In this assignment, we implement a function that simulates the outcome of tossing of 3 dice.
//We will learn how to generate random numbers, and how to seed a random number generator.
//For example, we use the following code to generate a random number between 1 and 6.
// rand() % 6 + 1
//The following code set the seed of the random number generator to 12345.
// srand(12345);

#include <stdio.h>
#include <stdlib.h>
#include <assert.h>

//TO DO
//Implement a function named cum_prob below.
//This function takes an integer k, and a long integer trials as inputs.
//This function returns a double value.
//In the fucntion, we toss the 3 dice multiple times. The number of tosses is trials.
//We count the number of times that the outcomes of the 3 dice add up to at least k.
////And we then use this number and trials to calculate the probability that
//the sum of the 3 dice is at least k.
//Finally, we return this probablity.

//Do not change the following code.
int main()
{
   long n = 10000000;
   int k;

   printf("Enter k :");  
   scanf("%d", &k);
   assert(k>= 3 && k<=18);
   srand(12345);
   printf("P(sum of the 3 dice is at least %d) = %.5lf\n", k, cum_prob(k, n));
   return 0;
}

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

for(i=0;i<n;i++)

int b=rand()%6+1;
int c=rand()%6+1;
if(a+b+c>=k)
{
ct++;
}
}
return ((double)ct/(double)n);
}
int main()
{
long n = 10000000;
int k;

printf("Enter k :");
scanf("%d", &k);
assert(k>= 3 && k<=18);
srand(12345);
printf("P(sum of the 3 dice is at least %d) = %.5lf\n", k, cum_prob(k, n));
return 0;
}

Kindly revert for any queries

Thanks.
