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 myRand.Next(2,13); - ✔✔No, It's not possible
|| || || || || || || || || || || || || ||
to get the same experimental results with one random number
|| || || || || || || || || ||

|| || ||
d. RandNum = myRand.Next(0,4);
|| || ||
e. None of these - ✔✔c. RandNum = myRand.Next(1,4);
