EGR 1400 EXAM 1 QUESTIONS AND ANSWERS
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); - CORRECT ANSWER✅✅✅No, It's
not possible to get the same experimental results with one random number
