/*DIRECTIONS Write a program that simulates the rolling of two dice.  Your program should roll the two dice 50,000 times.

Use a one-dimensional array to tally the numbers of times each possible sum appears.

Display the number of times each sum appears and its percentage out of the total numbers of rolls.  In other words,
calculate the probability of each sum using the law of large numbers.
