- ou have 2 six sided dice and you want to know how often and what percentage of each combination is rolled for a designated number of rolls. Ask the user how many times they want to roll the 2 dice. Use the random number generator to produce 2 numbers in the range of 1-6. This will simulate each dice. For output, show what each dice was for each roll (Use a loop to do this) and then print a summary report of how many of each total you rolled. The summary report will show how many rolls were made, how many of each total (remember totals will be 2 - 12) and what percentage each total was from all the rolls (number of that total/total rolls *100). Example Below. Be sure to ask the user if they would like to run the program again (Hint: Be sure to carefully place your play again while loop so that all the counters can be reset to 0 to play the game again. Summary report: Number of Total Rolls of the Dice: 500 Sum of Two Dice Number Percentage 50 10% 100 20% 12 1%Among 20 concrete cylinders, marked 1, 2, ...20, the total number of possible samples of 5 cylinders each is:Suppose that a course has 3 sections with 50, 70, and 80 students, respectively.
