//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);

//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.
