In C#, you can simulate rolling two dice by selecting a random number between 1 and 6 to
represent each die roll and then adding them together to get the dice total. Let,s say that we
developed a program to do this and we rolled the pair of dice 50 times and recorded the
results of each roll on a sheet of paper. Can we just select one random number between 2 and
12 and achieve the same experimental results for the 50 rolls as rolling two die and adding
them?
a. No, It's not possible to get the same experimental results with one random number
b. Yes, using the same scaling as before
c. Yes, if the Visual C# code is written to scale the single random number between 2 and 12
d. Yes, if the random number is selected using my land Next (2,13); - ANSWER No, It's not
possible to get the same experimental results with one random number
