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); Answer -
No, It's not possible to get the same experimental results with one random
number
What property of a Label control would you need to set to change the words

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